Description Tomas Pavek 2002-10-25 14:42:47 UTC 
One WeakListener created in ClassChildren (see the
attached stacktrace) is used multiple times - also
for listening on sub-elements of the class
(fields, methods, constructors). I guess it
happens in ClassChildren.hookNodeName(). When the
referenced listener is freed, the WeakListener
removes itself automatically only from
ClassElement it was originally created for, but
not from all the sub-elements. So e.g. with each
opening of a java file (see issue 27563), one more
WeakListener is leaked plus bunch of
LinkedList.Entry (used to store listeners in
ElementImpl).

Forgot to mention: this is in trunk, build 200210240100. Don't know
how this will change in projects, but this is rather subtle problem
that can generally happen on many places.
