[rules-users] Drools 5.6

[Jonathan Knehr]

When is 5.6 going to be officially released? 

There are many critically buggy things going on in 5.5 where the entire RightTupleIndex is getting very corrupted. I still haven't been able to produce a standalone unit test, but the issue always involves rules with "exists" and "not" in combination with complex retractions. Never does it happen with a few events, but when you run the scenarios over and over again millions of times, eventually the index becomes so corrupt that almost every single activation throws NPEs in MVEL, in the generated byte code, and in the rete data structures themselves to the point where all rule firing stops working.
