[jboss-jira] [JBoss JIRA] (DROOLS-152) NPE during benchmark in LeftTupleIndexRBTree.remove

Geoffrey De Smet commented on DROOLS-152:
-----------------------------------------
Moved to project Drools as this is a bug in Drools (even though I 'll accept a
reproducer using OptaPlanner).
[~arno_hernach] Without a reproducer, it's unlikely that we 're able to isolate
and fix this issue.
Can you create a reproducer (unit test or project that reproduces it) with as little as
rules/data as possible and attach it to this issue?
