Bug#468334: gcj-4.3: fails running unit tests from Lucene package where Sun JDK works

[Jan-Pascal van Best <janpascal@vanbest.org>]

Package: gcj-4.3
Version: 4.3-20080202-1
Severity: normal

The Lucene package contains a large number of unit tests. All tests succeed when
building using Sun JDK 5. When building using gcj-4.3 (with gcj-java-compat-dev
from unstable), quite a few unit tests fail. Upon a suggestion by Michael Koch
I'm filing a bug report to gcj with this issue, in the hope of pointing to more
concrete bugs in gcj.

Way to reproduce:
$ apt-get source lucene2
$ cd lucene2-2.3.0+ds1
(install dependencies including sun-java5-jdk)
$ debuild -i -us -uc
(observe the package builds without errors)
$ vi debian/rules
(change JAVA_HOME to /usr/lib/jvm/java-gcj and :wq)
$ debuild -i -us -uc
(observe unit test failures in build log)

I'll attach a list of the failed test cases as a reply to this bug.
