Eclipse SIGSEGVs in libpango

known problem with packages provided from eclipse.org. please use the one from the distribution (karmic)

Same problem, but slightly different software:

Eclipse is installed manually but up-to-date (3.5.1)

JRE version: 6.0_16-b01
# Java VM: Java HotSpot(TM) Client VM (14.2-b01 mixed mode, sharing linux-x86 )
(from package sun-java6-bin, version 6-16-0ubuntu1.9.04)

My question: WHY do i have to use eclipse from the distribution? There is nothing special to eclipse - it could also be every other SWT application...

libpango1.0-0, Version: 1.26.0-1

Also see strange behaviour when clicking buttons. Mostly they feel like i did not release the mouse button and then i have to press RETURN to start the action...

I also experience that button behaviour, but I think this is not related. Would you mind to create a bug report for that?

"it could also be every other SWT application" - ACK. If Eclipse is able to crash the JVM, every Java program could, right?

@nh2:
I see, you use openjdk 6. i use sun-java6-bin. and my eclipse is manually installed, so it uses only the standard dependencies from ubuntu. which package should I assign such a bug to?
I also see that eclipse process does not terminate anymore, but the all its windows and the profile lock were close correctly. system monitor tells futex_wait_queue_me.

And yes: I dont have any SWT testing application to check but i think it is a general problem.

@Daniel:
You should create one bug for each problem (I see the futex_wait_queue_me, too) and assign it to the Eclipse package - if somebody knows that it belongs to another package, he will just change it.

By the way, I have these bugs with both OpenJDK and Sun's Java.

@nh2:
I see there are already bug reports, and workarounds for both too:
Termination: Bug #293849 & Bug #299828
Buttons: Bug #443004

Confirm. I have installed eclipse from repo. And it's not working with both OpenJDK and Sun's Java.

the vm crash report in comment #8 seems to be incomplete

% opt/eclipse3.5/eclipse

you should report this problem where you got this version

@ Matthias:
It's the current "Eclipse IDE for Java Developers" available on eclipse.org.
I've filed the bug against OpenJDK because I do not know how a Java program can crash its JVM - why could that happen?

native code as distributed by eclipse.org, especially swt-gtk, xul and the like.

I found a upstream bug in https://bugs.eclipse.org/bugs/show_bug.cgi?id=291128

This happens with Karmic's Eclipse package, too.

To reproduce:
sudo apt-get install eclipse
eclipse
Click Help -> Install new Software -> Cancel -> You get the SIGSEGV

This happens with Karmic 64bits too.
I've tried everything:
-Ubuntu's Eclipse package
-Install manually Eclipse
-Delete ~/.eclipse

And it's just like #15

(Un)Fortunately, this does not happen on every system.
My Karmic Netbook sigsegvs while my Karmic Desktop does not.

Does your netbook have intel video? I have this problem on my HP 530
laptop. Can someone try it on non-intel video environment, please?

This appen to me too.

I'm running sun jdk from karmik repo, ati radeon 3200, intel core 2 (sony notebook).

Eclipse crashes everytime i click a "cancel".

So you if you want to reproduce this, just: File -> Import -> click cancel.

And you'll get this:

# SIGSEGV (0xb) at pc=0x002bd856, pid=4776, tid=3078371008

We found a workaround in Bug 460104.
Click System -> Preferences -> Assistive Technologies -> Untick first checkbox and re-login, Eclipse should work now.

Confirming that disabling Assistive Technologies prevents the pango crash. However, I still have the button interaction issue where I need to use the keyboard to press a button.

@Arlo:

isn't it bug 442078 ?

it should already be fixed in the repository version...

as a workaround for my old manual eclipse install i created a shell script with this line:

export GDK_NATIVE_WINDOWS=true && ./eclipse

thanks nh2 and Dario Bertini
Eclipse Galileo ( and 3.6XX) is working properly in Ubuntu 9.10 32bit after these tips :)

I don't have Assistive technologies in my Preferences, does anyone know how to get it?

Open (in a terminal or alt+f2) gnome-at-properties

turning off assistive technologies did not help me, eclipse (galileo SR1 from eclipse.org, not from repos) was still crashing when trying svn checkout (tigris.org subclipse plugin). The cure was as follows:
remove/rename libcairo-swt.so in eclipse folder to something that is not recognized as shared library, for example libcairo-swt.notsoso
apt-get install libswt-gtk-3.5-jni (i have karmic-proposed repos enabled so i got 3.5.1+repack~1-0ubuntu3 but it might work with earlier versions as well)
run eclipse and code away

apparently it did let me run checkout only once, now it crashes again :(

Can not confirm the workaround in #27 worked for me.
@Raivis: Did you restart your session after disabling assistive technologies?

The packages for Eclipse Galileo that are in Ubuntu's repositories (3.5.1+repack~1-0ubuntu1) do crash in Ubuntu, but do run in Kubuntu.

An example (that is not the only way of making Eclipse crash in Ubuntu in this way):

On Kubuntu:

Install Eclipse with K package manager or whatever.
Launch Eclipse
Click "Help" - "Install new software"
Setup Galileo repo
Select section "Programming Languages"
Select "Eclipse C/C++ Development Tools"
Click "Next" (Eclipse calculates dependencies, then shows you the packages you are going to install)
Click "Finish" (Eclipse downloads and installs CDT).

On Ubuntu:

Install Eclipse with Synaptic.
Launch Eclipse
Click "Help" - "Install new software"
Setup Galileo repo
Select section "Programming Languages"
Select "Eclipse C/C++ Development Tools"
Click "Next" (Eclipse calculates dependencies, then shows you the packages you are going to install)
Click "Finish" (Eclipse crashes and disappears).

If on Ubuntu Eclipse was launched from a console, at the moment it crashes you get this console output:

   #

Pixie dust recipes that did not work:

* Install clean download from eclipse.org (same behavior)
* setting GDK_NATIVE_WINDOWS=1 before launching Ubuntu repo or eclipse.org version (same behavior)

I insist: It DOES work OK in Kubuntu.

uhm, very interesting!

Does Kubuntu have "assistive technologies" ?

Andrea

Oh, I had missed the bit about relogging after disabling assistive technologies. I hereby confirm that disabling assistive technologies and relogging did make Eclipse work.

It is funny that it works out of the under Kubuntu, when it calls GTK just the same. I imagine GTK under Gnome does use Gnome libraries, and not only the other way around.

I can not turn off assistive tecnologies because I am blind and need to use eclipse with orca.
For while I'm using eclipse with windows. A solution would be welcome.
Thanks.

Now I cannot do checkout using Subversive plug-in. Turning "Assistive
Technologies" off does not help any more.

@ Oleksandr:
Could you tell us steps to reproduce?

To reproduce try the following steps:
1. Download and install eclipse 3.5.1 from http://www.eclipse.org
2. execute eclipse.
3. Press alt+h and chose install software.
4. press the cancel button.

Hi I use the GDK_NATIVE_WINDOWS but it does not resolve the issue for me.

When I do an SVN update or commit, the eclipse GUI freeze and become blue with no interaction possible. It happen no every times but 50% of the times.

I think it is due to credential dialog but I'm not sure of this.

Anyone has my same issue?

@ Jose: This is clear to me, but it seems that Oleksandr's Eclipse crashes only on Subversive checkouts and not on the original bug on cancel buttons.
@ Oleksandr: Is this right?

Hi, I solved my bug on #37 by use SvnKit instead of javaHL.

Another steps to reproduce:
1) Run Eclipse
2) Go to "Window -> Preferences -> General -> Keys"
3) Click on "Cancel" - Eclipse crashes
Disabling gnome assistive technologies helped me.

Used SW:
Ubuntu 9.10, amd64
Eclipse 3.5.1

In my opinion it's more related to GUI components rendering (tree view for example).

Since the bug seems to be related to assistive technologies, I wrote to Li Yuan, the person responsable to maintaining the at-spi.
I received the following reply:

------
From the trace, I don't find any accessibility code. Although it is not a complete trace, it would be great if we can get the full trace.
------

Is it possible to generate a full trace? What steps?
Thanks.

It seems to be a fix to this bug. I didn't try yet.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=291128

As described above, a patch has been created in the upstream bug.
I have created an SWT jar using it.
Place it into your Eclipse 3.5.1 "plugin" directory and your crashes should stop.
Please report back if it works.

Perhaps I am doing something wrong.
sudo apt-get install eclipse
cp -i org.eclipse.swt.gtk.linux.x86_3.5.1.v3555a.jar /usr/lib/eclipse/plugins/

The crash persists.
I am running eclipse in a 64-bit environment, may be the difference?
I gave a try in eclipse 3.6 I20091204 and no crash.

Hi

The jar file attached by nh2 only works for x86 machines - amd64 needs a different one. Nevertheless, we will look into backporting the patch for this problem from eclipse 3.6 - I hope (but cannot promise) that we can get it backported to Karmic (or into proposed-updates)

~Niels

Here is a jar for 64 bit.
Please try if it works and make a backup of your original one before - I cannot test it because I have no 64 bit system available here.

Works fine with file attached in coment 47.
I'll try more tests.

From I noticed that if GTK_MODULES contains "atk-bridge" eclipse keeps crashing.

Default GTK_MODULES:
jarkko@sentti:~/dev/eclipse$ !echo
echo $GTK_MODULES
canberra-gtk-module:gail:atk-bridge

My eclipse startup script, which doesn't crash eclipse:
jarkko@sentti:~/dev/eclipse$ cat eclipse
#!/bin/sh

echo https://bugs.edge.launchpad.net/ubuntu/+source/eclipse/+bug/458703
export GDK_NATIVE_WINDOWS=1
echo https://bugzilla.gnome.org/show_bug.cgi?id=546542
export GTK_MODULES="canberra-gtk-module:gail"

~/dev/eclipse/eclipse.bin $0

Notice that eclipse.bin reads eclipse.bin.ini (not the default eclipse.ini). Also empty (GTK_MODULES="") works also.

I am also seeing this crash in Xubuntu 9.10 Karmic on my laptop (amd64 HP nc6320 with intel 945GM graphics) but not on my desktop (also amd64 but with nVidia 9500GT graphics). Other than the graphics drivers, the two systems are setup with the same software.

I have installed eclipse from the apt repository so the GDK_NATIVE_WINDOWS workaround is in place and the buttons all work fine.

Xubuntu appears to not have the assistive technologies at all, so I can't turn it off (the package at-api is not installed).

I have subclipse 1.6.5 installed OK and the javaHL is working. Some of the subclipse functionality works but checkouts fairly reliably cause a libpango crash similar to above on the laptop only. I think I have seen it work occasionally when I haven't changed anything, but usually it does crash.

I have tried renaming libcairo-swt and using the 64-bit org.eclipse.swt.gtk.linux.x86_64_3.5.1.v3555a.jar from #47, neither has any effect.

Will most probably be fixed in Eclipse 3.5.2.

The fix suggested in #3 of https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/500776, (marked as a duplicate of this) does not help for me.

It says that the pango crash is due to a bug in libglib2.0-0 version 2.22.3-0ubuntu1 and suggests downgrading it to 2.22.2-0ubuntu1.

The libpango crash after running subclipse update remains the same here so this does not appear to be the case.

As You suggested I've downloaded Eclipse 3.5.2 RC1. The problem still occurs.

thinkpad /my2/download $ /usr/local/eclipse-SDK-3.5.2RC1-linux-gtk-x86_64/eclipse

Ahh, and I forgot to mention that downgrade of libglib-2.0-0 from v 2.22.3-0ubuntu1 to v 2.22.2-0ubuntu1 did not help anyway. Previous versions of stable ganymede and galileo also crash after just few minutes after startup and usage.
Is there anybody who could just debug the problem and close this bug request ?

Hi

We imported a patch from Fedora and expect this issue to be fixed with the next upload.

~Niels

Hi!

Thanks for Your efforts!
Could You please clarify if I should download new eclipse from eclipse.org or just run KPackageKit to download a patch You were speaking about in a previous post ? Would You be so kind and describe little closer what was the core of the problem ?

M

Hi

What I meant is that we have imported a patch from Fedora to our source repository and with our next build/upload to Ubuntu, this bug should be dealt with and you will then be able to download a patched version of eclipse via KPackageKit. I am unsure if the packages from eclipse.org has been fixed - the fix is scheduled for their 3.5.2 release, but I do not if it made it into the RC2 released recently.

So, unless 3.5.2RC2 contains the fix, I guess the answer is to wait a bit. I am guessing your next question will be "when will the patched eclipse be available?". I do not know yet, I will have a chat with Benjamin about it.

As for the core of the problem: From what I can tell (by looking at the patch), it seems that a NullPointerException in some java code caused it. I think (but I honestly do not know) that the error was incorrectly reported as being in libpango. I admit that I have not been paying too much attention to the actual cause for it (I only looked for the patch). If you want the full story, I can recommend reading the eclipse bug linked from here - it may even know if eclipse 3.5.2RC2 contains the fix.

~Niels

This version has not fixed the issue for me.

I installed with dpkg all of eclipse-*_3.5.1+repack~3-0ubuntu2_amd64.deb from here:
https://launchpad.net/ubuntu/lucid/+source/eclipse/3.5.1+repack~3-0ubuntu2.

I had to temporarily shift my source.list to the lucid repo (in karmic) to allow all the other dependancies (libcommons-stuff etc) to upgrade accordingly.

The libpango crash still occurs when trying to run subclipse update.

This is more irratic now.

After a few times restarting eclipse and attempting subclipse update.
- Twice I've had libpango crash as before.
- Three times it just gives lots of NullPointerException under org.eclipse.swt.widgets.Display.fixedSizeAllocateProc(Display.java:1281).
- Three times eclipse has just frozen.
- Once I've just had "Fatal IO error 11 (Resource temporarily unavaliable) on X server :0.0"

I would suggest that there might be a bug in subclipse itself, since it also uses native code (javahl), but the NullPointerException seems to occur through subclipse's use of swt, not through any calls to SVN.

My desktop machine (same version and setup of everything) has never failed to work under heavy use, the laptop meanwhile has never worked once. I'm at a loss as to how to investigate further. Anything I can try?

Using Subversive, one can switch between JavaHL and SVNKit as SVN implementation.
If this is possible in Subclipse, too, you could try SVNKit and see if it changes some of your errors.
This is of course not related to your SWT problem.

Hi oliford

Could you please attach your crash log (should be named something like hs_err_pid<number>.log) with the new eclipse ?

~Niels

This was using the eclipse packages from the main lucid repository.

Hi again

Your problem is that eclipse have extracted (one of) its swt libraries into your home folders; which means it is still using the old defective version rather than our patched version.

Try deleing
/home/oliford/.eclipse/org.eclipse.platform_3.5.0_155965261/configuration/org.eclipse.osgi/bundles/144/1/.cp/libswt-cairo-gtk-3555.so

if that does not work, try to rename (or delete) ~/.eclipse. If you can still reproduce it after the removal/rename of ~/.eclipse, please provide the new log.

Thank you in advance,
~Niels

Ok, I decided it would be best to go for the full:
rm -r ~/.eclipse
sudo apt-get --purge remove eclipse eclipse-platform eclipse-platform-data eclipse-...
sudo apt-get autoremove
(That also got rid of libswt-gtk-3.5-java, which never came back)

sudo apt-get install eclipse

Starting eclipse at this point gave me "java.lang.NoClassDefFoundError: org/eclipse/core/runtime/adaptor/EclipseStarter" and I had to --purge remove and reinstall libequinox-osgi-java to fix that.

Eclipse now ran again, but still crashes on subclipse update. Log attached.

Thanks

Just to rule one more thing out...

You might notice my options also include a -Djava.library.path=/usr/lib/jni. It is there so subclipse can find libjavahl.

That directory also contained some libswt-... stuff so I tried copying the libjavahl to elsewhere and changing the option to that dir incase it was causing problems but it doesn't stop the crash.

Karmic 64 bit here too, same crash.

Turning off Assistive Technologies did NOT fix this for me.

export GDK_NATIVE_WINDOWS=true
./eclipse

does work for me (fix care of http://ubuntu-virginia.ubuntuforums.org/showpost.php?p=8145665&postcount=3)

^^^^ did not work for me. Karmic 64 bit and the following:

bladernr@klaatu:~$ apt-cache policy eclipse-platform
eclipse-platform:
  Installed: 3.5.1+repack~1-0ubuntu3
  Candidate: 3.5.1+repack~1-0ubuntu3

This is quite annoying, really. And I'm not even using Eclipse for Java coding... I'm using it for Python :(

Bollocks. I also tried Niels suggestion in #64. I moved .eclipse and started eclipse. It launched, and as soon as I tried installing pydev, java crashed.

New crash attached...

Hi Jeff Lane

The reason why you are seeing this issue is because the bug has been fixed in lucid but not karmic. We will attempt to back-port it to karmic-updates.

jknight: if that work-around works, then you are not using eclipse from Ubuntu (because it sets this variable for you already).

oliford: I am afraid I do not have any news for you on why this is happening - maybe the patch we got is only partial, maybe the svn plugin is broken. Have you tried the alternative svn implementation? The SVNKit or whatever it is called?

~Niels

Iirc, I did try the java SVNkit and the crash occured exactly the same.

The lucid eclipse was also occasionally crashing when I wasn't doing anything with subclipse, so I've now rolled my laptop all the way back to Jaunty (and am putting up with other bugs instead).

I have a spare partition on the laptop so will try lucid and eclipse again whenever any new updates or ideas get mentioned on here.

Thanks for your efforts,
oliford

Cannot checkout svn projects using subclipse (it crashes on downloading project info), cannot update/install plugin software (crashes after clicking cancel or install). Just about anytime a pop-up window gives you the option to cancel (like creating a new project), eclipse crashes. Disabling assistive technologies didn't work. Installing the jar listed above does not help. Running ubuntu karmic on a dell laptop.

@zenith

i'm too seeing this in eclipse subversion commit dialogs

Linux box05 2.6.32-02063209-generic #02063209 SMP Wed Feb 24 10:09:53 UTC 2010 x86_64 GNU/Linux

Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) 64-Bit Server VM (build 16.0-b13, mixed mode)

I don't know what changed, but it's working perfectly now. I ran the following updates and now everything seems to be working perfectly:

# apt-get update
# apt-get upgrade
# apt-get dist-upgrade

I've made a fresh install of lucid beta1 with eclipse and subclipse.

It did freeze (but not crash) the first time I tried to update with subclipse but on the second attempt and every attempt since, it has worked perfectly. No signs of the libpango crash so this bug is fixed from my point of view.

Thanks everyone,

oliford

The problem is easily reproduced when one tries to add software sources like so:

http://wiki.eclipse.org/PDT/Installation#Eclipse_3.5_.2F_Galileo_.2F_PDT_2.2

After saving the config, eclipse crashes.

I've attached the logfile.

Thanks

The problem went away when I disabled assistive technology: System -> Preferences -> Assistive Technology -> Uncheck the checkboxes, logout, login. Problem solved.

@Allard Hoeve

I've been experiencing this problem and never had any of the Assistive Technology options enabled.

I'm running eclipse installed from the Ubuntu Karmic repository, along with OpenJDK, on an Asus EeePC 1000H.
I happened to click Window -> Preferences -> OK on eclipse, and it produced these two consecutive errors in an error report within the IDE (see below):

Update:
Turning off Assistive Technologies (gnome-control-center) did solved the SIGSEGV problem.
(I tried running a eclipse -clean before turning off the A.T.).

Update 2:
I appologize for spamming the thread with comments. I spoke a little too soon: turning off Assistive Technologies did *NOT* solve the problem. (It merely seemed to prevent a crash on another window.)

So in essence, Eclipse crashes when hitting Cancel on the "Help -> Install new software" menu.
(BTW, with other windows such as File -> Open the decorations seem to be native from the desktop. I suppose this is on purpose.)

Anyway, below is a run done with gdb. A lot of the SIGSEGV do not manifest when running "normally"; a few of them don't seem to show up when doing export GDK_NATIVE_WINDOWS=true before running the gdb session.

I'm experiencing this problem too in a fresh install of Lucid beta2 with all updates done until now. Even disabling A.T. and setting GDK_NATIVE_WINDOWS=1 don't fix the problem. Eclipse freezes soon at the splash screen when it's showing the message "Loading workbench". The weirdest thing is that Eclipse have been working fine until I did some apt-get updates yesterday.

Hi

Could you please attach /home/duno/hs_err_pid2685.log to this bug?

Thanks,

Looking at the log, I can see that you are using a local eclipse and not
the one from Ubuntu. We cannot support versions of eclipse that we have
not uploaded.

Furthermore, you have swt libraries present in your ~/.eclipse. These
will cause problems if you change the eclipse or at next upstream release.
  Currently any Ubuntu installed eclipse will use the libraries in your
~/.eclipse and not the ones we provide. This means that some of the
Ubuntu patches will be ignored and may very well be the source of crashes.

Looking elsewhere, I happened to find a solution here:
https://www.digisoftinc.org/wiki/index.php/Linux_Notes#Eclipse_3.4_and_Ubuntu_9.10_Fix
It's not clear whether the author(s) discovered it by them/him/herself or whether copied+pasted from somewhere else.

For reference, it involves installing xulrunner and editing eclipse.ini, i.e.:
1. sudo apt-get install xulrunner
2. echo '-Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner' >>/usr/lib/eclipse/eclipse.ini

After doing these two steps, I restarted eclipse. The SIGSEGV on pressing the Cancel button on the Install new software ... menu no longer happens.

Please note: This solution is also reported in bug #393091

Invalid for Karmic. Fix Released upstream but since Karmic is EOL, there's no need to keep this open there.
