The CxfBusLifeCycleManager can cause ConcurrentModificationExceptions to be
thrown
----------------------------------------------------------------------------------
Key: CXF-2105
URL: https://issues.apache.org/jira/browse/CXF-2105
Project: CXF
Issue Type: Bug
Components: Core
Affects Versions: 2.0.10
Reporter: Eamonn Dwyer
Fix For: 2.0.11
The CxfBusLifeCycleManager has a list of listeners. in a number of occasions
it iterates over this list and makes calls out to each listener. Each listener
can then call back into the CxfBusLifeCycleManager and potentially try access
the listeners. This causes the exception. Typically the exception thrown looks
like.
