[infinispan-issues] [JBoss JIRA] (ISPN-2372) Memory leak in AbstractJBossMarshaller

Memory leak in AbstractJBossMarshaller -------------------------------------- Key: ISPN-2372 URL: https://issues.jboss.org/browse/ISPN-2372 Project: Infinispan Issue Type: Bug Affects Versions: 5.2.0.Beta1 Reporter: Marko Lukša Assignee: Dan Berindei Priority: Blocker Fix For: 5.2.0.Final {{AbstractJBossMarshaller.marshallerTL}} is leaking {{PerThreadInstanceHolder}} instances. These hold a reference to {{MarshallingConfiguration}}, which indirectly holds a reference to the classloader, which of course holds a truckload of stuff. The cause of the leak is the fact that noone ever calls {{remove()}} on {{marshallerTL}}. I've tried adding {{marshallerTL.remove()}} to {{AbstractJBossMarshaller.stop()}}, but this only removed references from JBossAS' MSC Service threads. Other threads (in my case only one thread - "http-/127.0.0.1:8080-2") are still causing the leak.
