Could you try 5.6.0-SNAPSHOT?
Thanks

I'm trying to update our application from Drools 4.0.7 to Drools 5.5

All the rules compile and I am serializing the KnowledgeBase and
reading it in upon application start-up.
Inserting facts works find. Retracting can often return the
NullPointerException shown below. That clip comes from a unit test
that literally just inserts 10 "TestFact" objects and then tries to
retract them one at a time. No rule firing happens, just insertion
and retraction. I did try adding a rule firing in between the insert
and retraction loops but it made no difference. These "TestFact"
object don't actually trigger any rules if that matters.
I've tried this with both the Drools 5.5.0.Final and 5.3.0.Final jars
with the same results. Searches on the forum and on Google show this
as a bug in 5.5.0.Final, but say it should work in 5.3.0.Final. It
doesn't work on either for me.
I am going to try some variations on this test, but it seems like this
should work as-is.
Any suggestions would be greatly appreciated.
