Handle duplicate events in drools-apps
Modified the frankfurt rules to compare the event objects instead of comparing the request ID when determining if an event is new. The event object's equals() method ignores the request ID when doing the comparison, thus it will treat an event as a duplicate even if the request ID is different, which is the behavior we want. Also removed the @Ignore from the junit that tests for duplicate events in the hope that this change will fix it. If the docker build still breaks, then @Ignore can be added back in. Issue-ID: POLICY-2557 Change-Id: If2b9fd26473d78a356218b951bfe160f93daeb32 Signed-off-by: Jim Hahn <jrh3@att.com>
