I really appreciated that.

ant will give the tests 512MB heapspace and some of the tests go near
this during execution. Yet, your IDE might not provide enough
heapspace so you should try to figure out how to give junit more
heapspace when running. The reason why those test didn't fail when you
run them in isolation might be due to our randomized testing. We
select a lot of things at random which gives you basically a different
setup for each run.

when you run ant eclipse what do you mean by not as clean? can yo
gimme more details? Sorry I can not help with IDEA :)

I dunno if I did something badly.
