[jira] [Commented] (CXF-3801) EndpointReferenceUtils.convertToXML()
causes ConcurrentModificationException under load
[ https://issues.apache.org/jira/browse/CXF-3801?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13102939#comment-13102939 ]
Daniel Kulp commented on CXF-3801:
----------------------------------
Oli,
How easy is it for you to reproduce and test this?
I just discovered the call in JAXBContextCache to "remove" was not in a synchronized block which could definitely cause this. I'm committing that fix to trunk and the branches, but would definitely like to see this tested to make sure it really fixes the problem.
