ExceptionUtils not thread-safe
------------------------------
Key: LANG-369
URL: https://issues.apache.org/jira/browse/LANG-369
Project: Commons Lang
Issue Type: Bug
Reporter: Sebb
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.
