Same criteria across multiple rules cancels activation with Property Reactive Facts

When using property reactive facts, if 2 or more rules have the same criteria this causes an unexpected cancel of the rule activation.

As objects are inserted into the engine, the activations are created as expected but after an activation is fired on a rule, any other rules that have the same criteria get their activation cancelled.

If all the rules have a different criteria then all works fine. If you switch off property reactive mode then all works fine.

I cant seem to add attachments to this jira but i have added all the attachments and unit tests to the following forum post:
