[seam-issues] [JBoss JIRA] Updated: (JBSEAM-4576) Upgrade Javassist to new version - current version has memory leaks

Upgrade Javassist to new version - current version has memory leaks ------------------------------------------------------------------- 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.
