Prevent AAI re-query
Modified event manager code to not query AAI if there's already a response from a previous query. Modified code to store AAI properties in local variables instead of static to prevent any chance of a race condition in a multi-threaded situation. Updated junit tests to use a new manager for each subsequent query. Update license. Change variable name, in junit test, from onsetEvent to event, because it can be any type of event. Included fix to prevent initial AAI query if AAI data was already available in the initial onset event. Change-Id: Idf3e15ea8c5e297f22f23570c22fd837b72ba200 Issue-ID: POLICY-754 Signed-off-by: Jim Hahn <jrh3@att.com>
