OptaPlanner 6.0.1. While it works far better for the time it runs, it uses<br>

<br>
with:<br>
Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: GC<br>

<br>
Is there a way to limit how much memory OptaPlanner uses? Or is it likely<br>
that I'm just adding fact to the WorkingMemory in a way that wasn't a<br>
problem in 5.5 but is a problem in 6.0?<br>
