A workaround in optaplanner 6.0.1 is probably to enforce RETE_OO
(unfortunately ScoreDirectorFactoryConfig#buildKieBase hard codes that,
so that's a PITA).
It's fixed in BRMS 6.0.0.GA and optaplanner 6.1.0.Beta1.
optaplanner 6.1.0.Beta1 might be released later this month.

I've converted some NurseRostering rules, which worked in Drools
5.50, to
OptaPlanner 6.0.1. While it works far better for the time it runs,
it uses
up whatever memory I can give it (9GB) and then eventually crashes
the GUI.
with:
Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: GC
overhead limit exceeded
Is there a way to limit how much memory OptaPlanner uses? Or is it
likely
that I'm just adding fact to the WorkingMemory in a way that wasn't a
problem in 5.5 but is a problem in 6.0?
