> If I set my rule base to use equality-based assert behavior, I'm expecting to be able to use the getFactHandle(object) method to retrieve a previously asserted fact by providing an equivalent (by equals() and hashCode()) object as an argument. This appears to not be the case, as AbstractWorkingMemory uses it's identityMap and associated IdentityAssertMapComparator to do the getFactHandle lookup instead of the assertMap and EqualityAssertMapComparator. This causes the lookup to be done with the system hashCode() method and not the overridden version supplied in my fact class. The lookup thus fails and returns null.
