[jira] Resolved: (LANG-262) Use of enum prevents a classloader from
being garbage collected resuling in out of memory exceptions.
[ http://issues.apache.org/jira/browse/LANG-262?page=all ]
Henri Yandell resolved LANG-262.
--------------------------------
Resolution: Fixed
I think my research class shows that things should work. Making it a unit test seems a lot more painful, which I'm finding very hard to have the energy for. Resolving this as fixed.

> When an enum is created it is placed in the static hashmap - cEnumClasses. If the enum is created from a classloader which has a limited lifetime then due to the strong reference the classloader is never garbage collected resulting in a memory leak.
> I believe that making the cEnumClasses a WeakHashMap should resolve the problem.
