java.util.ConcurrentModificationException on client with JAXBFrontend
---------------------------------------------------------------------
Key: CXF-1569
URL: https://issues.apache.org/jira/browse/CXF-1569
Project: CXF
Issue Type: Bug
Components: JAXB Databinding
Affects Versions: 2.0.6
Reporter: Marc Giger
I have a testcase where I do fire 100 ws calls in parallel. The test ends with
following stacktrace on the client side:
Every client is a new instance and not reused!
That's the first time I got this exception, so it seems very difficult to
reproduce.
