Seeing the selfprofiling on the stacktrace, I guess the OOME is related to the current problems with self-profiling, e.g. bug 183832, bug 183993 or bug 183201.

*** This bug has been marked as a duplicate of bug 183832 ***
Comment 3 Sergey Petrov 2010-04-16 10:46:07 UTC 
183832 is fixed but the issue is still reproducible.
also use case isn't related to 1 hour wait, so may be it's a duplicate of another issue, or one of fixed need to be reopened, any ideas?
Comment 4 Tomas Pavek 2010-04-19 16:09:50 UTC 
So same thing as bug 184345. The self-profiling takes much CPU and memory when saving a long snapshot. The OOME is from that. See also bug 183993.

Since the self-profiling bugs are filed elsewhere, we could use this one for tracking the original problem - AWT blocked for long time by the wizard (that's why the IDE tried to create snapshot).

Below is the problematic stacktrace. I agree this should not be called in AWT, OTOH the other option is to show a modal dialog (e.g. like the "Opening Project" one) and in fact block the user anyway. I wonder if adding the maven dependency should not be done asynchronously in this case.

java.lang.AssertionError:  Not to be called from AWT, can take significant amount ot time to download dependencies from the network.

Comment 5 Jan Stola 2010-04-20 09:51:12 UTC 
The creation of master/detail form has been moved outside AWT thread and an indefinite progress bar blocks the UI while the form is being generated.

The exception is no longer thrown but the creation still takes several minutes. The duration is not a problem of GUI builder. It is a problem (or feature) of Maven project. It seems that it has a lot to do - including download of indexes of both Central and Java.net repositories.
