APPC - OAM ConcurrentModificationException
Fixes: - In the AsyncTaskHelper, the cancel future augmentation in the scheduleBaseRunnable(...) removed itself from the myFutureSet while it was iterating over the entries. This caused the ConcurrentModificationException - The Timeout operation in the ConfigurationHelper was not converting the units to millisecond. - The Timeout in the BaseProcessor. preProcess(...) was NOT using the request-timeout value supplied in the request. - When a timeout occurred in the BaseProcessor. preProcess(...) method, the OAM state was not being switched to ERROR state Issue-Id: APPC-263 Change-Id: I02c5e3adaca9a595d2c3541d8a997f3254bf097a Signed-off-by: Joey Sullivan <joey.sullivan@amdocs.com>
