Question

I have a java junit test that passes when run alone on a development machine. We also have a hudson job which runs all the tests, invoked via ant, on a Mac OS X 10.4 node wi

Answer 1

For me, it was an "java.lang.OutOfMemoryError" in the forked VM (junit task with fork="yes") which made this message appear in the main VM.

The OutOfMemory was visible in the ant log (well, is visible since it's still present).

I use ant 1.7.1, so no hope with upgrading ant.

After putting the same VM parameters in "Run>External tools>External tools>JRE" than in Eclipse.ini (-Xms40m -Xmx512m -XX:MaxPermSize=256M) the problem is solved.

I keep fork to "no" to be sure ant use the parameters.
