threading issue
[ https://issues.apache.org/jira/browse/CXF-1560?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12593410#action_12593410 ]
Marc Giger commented on CXF-1560:
---------------------------------
Hi Daniel,
My patch was not meant to apply as is. It just should show the problematic code part, and the possible solution;-)
Your patch works as expected.
Is your patch against cxf-2.1? I've tested it with cxf-2.0.6
Thanks

> If I invoke a fresh started service once with a single thread and after that with multiple threads it works fine.
> The attached patch fixes that but I'm not sure if it's the right place and who is at fault here. The overhead by this patch should be minimal.
