PAP erroneously undeploying policies
The problem appears to be a multi-threading type of issue: - PAP sends request to XACML - JMeter pushes the next deployment request into PAP - PAP receives response from XACML - based on request ID, the response is routed to the handler, but blocks while PAP processes the deployment request - PAP replaces old list of policies with new, and changes the request ID - PAP responds to JMeter - PAP handles XACML response, even though it's request ID no longer matches Modified PAP to no longer replace any messages that are at the head of the queue. Fixed the license. Issue-ID: POLICY-2527 Change-Id: I43218a7d0591649d761e17282189e51d5dbd26ed Signed-off-by: Jim Hahn <jrh3@att.com>
