> Key: JBSEAM-4576
> URL: https://jira.jboss.org/browse/JBSEAM-4576
> Project: Seam
> Issue Type: Task
> Components: Core
> Affects Versions: 2.2.0.CR1, 2.2.0.GA
> Reporter: Marek Novotny
> Assignee: Marek Novotny
> Fix For: 2.2.1.CR3
>
>
> The problem is caused by the current javassist usage pattern of calling
> ProxyFactory.createClass().newInstance() which currently (due to the broken
> cache), always creates a new class for the proxy. And once this class gets
> classloaded, you cannot easily get rid of it from the ClassLoaders class map.
> There were also a few problems with deserialization, mainly because it did
> drop the assigned MethodHandler and used the DefaultMethodHandler instead.
> Storing a static reference cause a problem for garbage collection, because
> the MethodHandler set directly into the ProxyFactory can never get freed.
> Patches from Mark Struberg are available at
> http://github.com/struberg/javassist
