Memory leak cause by JavaUtils.enumMap
--------------------------------------
Key: AXIS-2278
URL: http://issues.apache.org/jira/browse/AXIS-2278
Project: Apache Axis
Type: Bug
Versions: 1.3
Environment: Sun JDK 1.4.2/WinXP
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...
