This problem may occur if multiple JAX-WS clients are running
in the same Java Virtual Machine and all of the clients use
the same JAX-WS handler list.

Problem conclusion

The JAX-WS runtime sorts the handler chain. If multiple
clients are using the same chain, a
ConcurrentModificationException error may occur.

The JAX-WS runtime is changed to use a copy of the handler
chain in the code that sorts the handler chain.  This change
avoids the error.

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.9.  Please refer to the Recommended Updates
