[DrJava] unit tests: java.lang.OutOfMemoryError: GC overhead limit exceeded

[<san...@gm...>]

Hello,

I want to work a little bit on drjava. It looks very nice.

I have set up an enviroment and tried to run the unit tests but they fail  
over time because of an OutOfMemoryError GC overhead limit exceeded. I have  
tried both with ant and within my eclipse IDE. Normally tests begin to fail  
after 500 tests.
Specially edu.rice.cs.drjava.ui.DefinitionsPaneTest: testGranularUndo seems  
to be the first one to fail.

I have tried to give more memory to my eclipse but this hasn't helped. Is  
there anything I could be doing wrong? drjava does build and if I try to do  
the tests in small groups they work.
I am using the openjdk 1.6.0_20 under an ubuntu 10.10 64bits SO.

Any hint would be appreciated.

Greetings.
