RE: [aspectj-users] java.lang.OutOfMemoryError: PermGen space whenweaving. 
Note that PermGen space errors are not always indicative of memory leaks,
e.g.:

129490: i am getting more and more out of PermGen space problems..
https://bugs.eclipse.org/bugs/show_bug.cgi?id=129490

Summarizing what we learned with Eclipse on that bug report, the thing to
try is to first make sure that you have the latest VM such as the Sun JRE 5
update 9 because some bugs related to PermGen space growth were fixed after
update 6 (if I recall correctly this error won't happen on JRockit or the
IBM VM).  If that doesn't resolve it try to raise your PermGen space to
something reasonable for your application, e.g. -XX:MaxPermSize=128m.  If
you still get the error after that, there probably is a leak so please do
create a bug.
