[ http://issues.apache.org/jira/browse/AXIS-2278?page=all ]
Kevan Miller updated AXIS-2278:
-------------------------------
Attachment: enumMapPatch.txt
Here you go... I checked out from current trunk. Built from the source and then
run under Geronimo. With the change, I don't see enumMap holding onto Geronimo
classloaders...
FYI, there's another potential leak around
o.a.a.description.TypeDesc.classMap/classMaps (1.3 is different than trunk? Not
sure why...). Either way, it's part of a chain of references that is keeping
ClassLoaders alive. I need to investigate some more... May be a Geronimo
problem. Will raise an issue, if I confirm there is a problem.
> Memory leak cause by JavaUtils.enumMap

> Key: AXIS-2278
> URL: http://issues.apache.org/jira/browse/AXIS-2278

> Type: Bug
> Versions: 1.3

> Reporter: Kevan Miller

> I'm chasing down some Geronimo memory leaks when deploying/undeploying the
> DayTrader sample application.
> One memory leak I see is caused by o.a.a.utils.JavaUtils.enumMap. JavaUtils
> is loaded by a parent ClassLoader but is has strong references to classes
> (the keys of enumMap) which were loaded by child ClassLoaders. This prevents
> the ClassLoader, and the classes it has loaded, from being GC'ed. This means
> we'll eventually run out of PermGen memory...
> I converted enumMap to be a WeakHashMap and I now see the ClassLoaders being
> GC'ed. I didn't download using cvs. So, I don't have a patch. I'm happy to
> generate one, if you'd like...
