Vitali Yemialyanchyk commented on JBIDE-4740:
---------------------------------------------

Denis, with you changes I had errors in junit tests on my machine. It seems magic LIMIT not suitable for my PC configuration... :)
Seriously, I opposite such hacks. The reason of memory grow is quickly open/close editors more then 880 times.
Here: http://dev.eclipse.org/blogs/memoryanalyzer/2008/04/21/immortal-objects-or-how-to-find-memory-leaks/
first string - start of the article: "This is a classic memory leak: Select Window -> New Window in your Eclipse IDE and then close the new window right away. The heap usage grows a little bit. Open and close a couple new windows and the heap usage grows more. That's what bug 206584 is about."
If this is principally to change memory usage for this JUnit - we should try to find other better way to fix this.
My current proposition is revert changes back...

> I've noticed tests amount of tests on hudson is jumping. It seems to depend on host where tests has been executed. The problem is OutOfMemoryException in hibernate console tests. I ran those tests localy and have a graph from jconsole for java heap (see attachment).
