that should work in eclipse too. Note that if your unit tests run out of
memory, it means your code is leaking somehow.
Look at http://java.sun.com/javase/6/webnotes/trouble/TSG-VM/TSG-VM.pdf
for some info on how to handle this. You can set up a forking JUnit to
to dump the heap on a memory overflow on recent java5 and all java6 JREs:
<jvmarg value="-XX:+HeapDumpOnOutOfMemoryError" />
this creates a heap dump that jhat can bring up in a web site for you to
browse round and debugl
