Hey,

As I want to understand the PermGen issue I digged a bit more on the web and
found a series of interesting posts about it from Frank Kieviet at sun.

It seems to be a complex problem involving cross classloaders relations between
classes that prevent the garbage collection of undeployed applications
classloaders.

Hope this helps.
