NullPointerException in FromNode.destroyCreatedHandles
------------------------------------------------------
Key: JBRULES-2796
URL: https://jira.jboss.org/browse/JBRULES-2796
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: drools-core
Reporter: Tommy Odom
Assignee: Mark Proctor
I received this NullPointerException after upgrading to drools 5.1.1. The
NullPointerException is being thrown when the rule executes "update($build);"
where $build is set in the LHS from a Build in working memory. I'm not sure if the
bug is that matches may be null and a null check needs to be added or if something else is
going on causing the tuple to not be found.

----------------------------------------
I am also getting this exception in both 5.1.0 and 5.1.1. It wasn't occurring in
5.0.1. I'm not getting it in 5.2.0.M1 so possibly it has been fixed already.

----------------------------------------
I am also repeatably getting this exception with 5.1.1. It appears to go away in 5.2.0.M1
for me too. I have not been able to get my rules to load on 5.0.1 to test that.

It seems this is now fixed in 5.2, so I'm closing. Anyone having this problem will
need to migrate to 5.2.
