Hello, I added custom build step to my project (it simply invokes rmic) and after serveral calls it crashes with (nothing in logs): BUILD FAILED java.lang.OutOfMemoryError: PermGen space Eclipse 3.2 eclipse.ini: -vmargs -Xms256m -Xmx768m See attached files for logs and configuration details.
Created attachment 47462 [details] my configuration
Created attachment 47463 [details] log with some exceptions
Log files only have exception about get javadoc on rt.jar which does not seem to be related with your current issue. Your configuration shows that you have installed Web Tools plugins on top of eclipse => reassign to this component for further investigations on this OOM...
Pavel, did you try launching Eclipse with -XX:MaxPermSize=128m, does this workaround the OOM error?
Seems to be working. But this parameter might only delay OOM exception. Need to test more thoroughly. Once I had rmic task hanging (couldn't stop Eclipse had to kill it with task manager).
Created attachment 47680 [details] Log file Had OOM and crash. With parameters you've sent me (see logs).
Hi Pavel, you said: Once I had rmic task hanging (couldn't stop Eclipse had to kill it with task manager). Is this rmic task written by you? I don't recall a rmic task in the WTP project. If this is something that's written by you, does it load tons of classes and methods, if so, that may explain why you are getting the perm gen OOM error. At this point, I do not believe this is a WTP bug unless we can reproduce the same issue just by invoking functions contributed by WTP.
I am not sure either. I submited it as JDT bug (custom Ant task).
Created attachment 47900 [details] my new configuration I removed most of the plugins and I still got this exception eventually. If I don't have custom ant build task everything is okay.
Created attachment 47901 [details] new logs These are my new logs
Still there in 3.2.1 :((((((
Another problem is that ANT build step doesn't work in 50% of the time if I have two projects, one has ant build step and another doesn't and latter depends on first one.
Created attachment 52063 [details] error message I've got when ant task is added to workspace with more than one project

I attched 2 screen shots with ant builder settings

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
