[jira] [Resolved] (CXF-4006) Possible classloader leak due to
ThreadLocal
[ https://issues.apache.org/jira/browse/CXF-4006?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sergey Beryozkin resolved CXF-4006.
-----------------------------------
Resolution: Fixed
Fix Version/s: 2.6
2.5.3
2.4.7
Assignee: Sergey Beryozkin
Sorry I did not catch the issue earlier; definitely fixed now, a temp regression spanning last 1-2 releases on 2.4.x/2.5.x
The leak should be more or less negligible, but the way to eliminate it with the released CXFs is to register a simple JAXBElementProvider (or/and JSONProvider) only which will override setMessageContext method and make it no-op.
MessageContext is needed to check for custom STAX handlers and may be Marshaller properties. This all can be managed in the custom provider using PhaseInterceptorChain.getCurrentMessage().
thanks

> org.apache.cxf.jaxrs.ext.MessageContextImpl is kept in a ThreadLocal for each HTTP request which means when a CXF-servlet-based webapp is undeployed, the webapp's classloader leaks.
> (At least, I think that's what's going on, I'm not that expert at tracking down memory leaks. Perhaps I have misconfigured something?)
