> The InterceptorProvider interface is essentially implemented by 2 classes in CXF: AbstractAttributedInterceptorProvider and AbstractBasicIntercetptorProvider.  The interceptor lists stored in these base types are implemented as ArrayLists.  However, ArrayLists are not thread-safe, so traversal of said interceptor lists is sensitive to underlying modifications by other interceptors or threads.  These maps should be implemented by the java.util.concurrent.CopyOnWriteArrayList type.
> Tested patch to follow.
