OpenJDK 7/8 don't generate .desktop needed by nautilus

Status changed to 'Confirmed' because the bug affects multiple users.

Ubuntu 12.04 LTS (32 & 64 bit) up-to-date
Lubuntu 14.04 LTS (32 & 64 bit) up-to-date

No openjdk-7-java.desktop file at /usr/share/applications

However, jar files are associated to openjdk-7-java.desktop at /usr/share/applications/defaults.list & /usr/share/applications/mimeinfo.cache

At Ubuntu 12.04 LTS (32 & 64 bit) up-to-date file openjdk-6-java.desktop exists.

Workaround. Create /usr/share/applications/openjdk-7-java.desktop similar to /usr/share/applications/openjdk-6-java.desktop

The contents should be:

[Desktop Entry]
Name=OpenJDK Java 7 Runtime
Comment=OpenJDK Java 7 Runtime
Exec=cautious-launcher %f /usr/bin/java -jar
Terminal=false
Type=Application
Icon=openjdk-7
MimeType=application/x-java-archive;application/java-archive;application/x-jar;
NoDisplay=true

Many people are claiming for this problem. Yo u can search it at Google:

missing openjdk-7-java.desktop

Status changed to 'Confirmed' because the bug affects multiple users.

/usr/share/applications/mimeinfo.cache has a line:

application/x-java-archive=file-roller.desktop;

and should be:

application/x-java-archive=openjdk-7-java.desktop;file-roller.desktop;

In fact, in a 12.04 LTS system with openjdk-6-java.desktop the line is:

application/x-java-archive=openjdk-6-java.desktop;file-roller.desktop;

I don't know if it is a bug or somebody decided not to permit the double-click for java files.

Changes at /usr/share/applications/mimeinfo.cache for double-click didn't work. I had to fix ~/.local/share/applications/mimeapps.list

[Added Associations]
application/x-java-archive=openjdk-7-java.desktop;

[Default Applications]
application/x-java-archive=openjdk-7-java.desktop

This can be done using [Open with] at file propierties or adding the "application" lines with a text editor.

" * Only install the openjdk-java.desktop file when using cautious-launcher."

Unsure what "cautious-launcher" is though

cautious-launcher is an Ubuntu-specific helper that ensures .jar files have the required executable bit set in order to comply with the following:

https://wiki.ubuntu.com/SecurityTeam/Policies#Execute-Permission_Bit_Required

The problem with openjdk is with this section in the rules file:

# .desktop files need to be multiarch installable
java_launcher = /$(basedir)/bin/java
java_launcher = /usr/bin/java
ifeq ($(distribution),Ubuntu)
  ifeq (,$(filter $(distrel),karmic jaunty intrepid hardy))
    java_launcher = cautious-launcher %f /$(basedir)/bin/java
    java_launcher = cautious-launcher %f /usr/bin/java
  endif
endif

I'm not sure why java_launcher is getting set twice, and I'm not sure why we're limiting cautious-launcher to older ubuntu releases.

Actually, I've read that wrong. I think the issue is the comparison here:

ifeq ($(java_launcher),cautious-launcher)

I bumped on this bug today in Trusty.
Both Java 7 from the official repositories and Java 8 from ppa:openjdk-r/ppa are missing the .desktop file.

I hope to see a fix in Trusty soon.
