>
> The ExceptionUtils class does not appear to be thread-safe:
> - CAUSE_METHOD_NAMES is not final, so may not be visible to all threads
> - addCauseMethodName() and removeCauseMethodName() can update
> CAUSE_METHOD_NAMES but are not synch.
> - all accesses to CAUSE_METHOD_NAMES probably need to be synchronised
> The documentation does not state whether or not the class is thread-safe, but
> given that it only has static methods it does not make any sense unless it is
> thread-safe.
