lucene2 jdk dependence

The problem is not with Sun JDK dependency. The problem is that one unit test fails on build servers since it can not get access to certain DTD hosted on internet. And this problem is independent of the compiler used.

The lucene2 core (and contrib) libraries build with GCJ also. I have already tried this by disabling unit tests. The solution to unit test failure is known but depends on another bug #183164.

Have patience. In about a week's time this will get fixed. :-)

Assigning to myself since I am going to fix this eventually.

Thanks Onkar, for working on lucene2 in Ubuntu.

I'm interested in building lucene2 with GCJ - you mention:

The lucene2 core (and contrib) libraries build with GCJ also. I have already tried this by disabling unit tests. The solution to unit test failure is known but depends on another bug #183164.

However I'm getting the following unit test failures:

Are these the failures to which you're referring?

Thanks and best wishes, Jack

Jack,

No the errors you are seeing are different. The one I was talking about is related to unit test 'testEncoding' found in contrib/highlighter/src/test/org/apache/lucene/search/highlight/HighlighterTest.java.
I never encountered the errors you are specifying because my build never got past the test that uses DTD.

Today I used some workaround for the DTD problem (bug #183164) and now I similar as the one you specified. I also found a reference to this on Debian pkg-java mailing list. http://lists.alioth.debian.org/pipermail/pkg-java-commits/2007-August/003771.html
I am not sure if this is GCJ specific error.
I will try to build the package with Icedtea and see if error persists. If it does not then building with Icedtea is 'the solution'. But this also means that I will have to add a patch for build scripts to specify target VM version as 1.5 else the resulting binary won't be usable with other runtimes. (Icedtea uses VM version 1.7).
If the error persists then I don't know what path I will have to take.

I have added a debdiff to bug bug #183164 and hopefully it will get accepted in a day or two. I will then fix lucene2.

@Marek,
Can you please attach a debdiff rather than .diff.gz so that I can check differences between your solution and mine and merge them if possible.

Attached. I did these changes to be able to build binary packages from source package.

Again in correct order. (Previous debdiff was in reverse order.)

Just for info: This is addressed/included in the patch for bug 189602.

This bug was fixed in the package lucene2 - 2.2.0-2ubuntu1
