Description pere 2006-05-08 11:08:38 UTC
When running openjump with the CVS version of GNU Classpath and jamvm, I get
a java.lang.StackOverflowError when I try to close the current map project using
the small x in the upper right corner of the internal window.  The problem
seem to be an endless recursion.  This is the start of the backtrace, including
the looping part.  I'll attach the full backtrace.

stack trace for the endless recursion
Comment 2 Roman Kennke 2006-05-08 13:53:24 UTC
I checked in a patch for javax/swing/DefaultDesktopManager.java into CVS HEAD. Could you retest this?
Comment 3 pere 2006-05-08 14:29:35 UTC
I tested, and now the endless loop error is gone, and I get two nullpointer
exceptions instead.  I guess that means this problem is solved, and a new
problem is exposed, but leave that decition to you.

Here are the two new backtraces:

Comment 5 pere 2006-05-08 21:24:08 UTC
I spoke with Roman Kennke on IRC, and he said the NPE issue should be reported
as a separate bug.  It is reported as bug #27511, and I am resolving this bug
as fixed.
