      After an updateToVersion where a rule is removed from the KieBase,
      fireAllRules fails with the exception below.

      Note: This happens with versions 6.4.0.Final-redhat-6 and later
      (including latest master)

      The following commit seems to be causing the NPE:
      https://issues.jboss.org/browse/DROOLS-1147
      https://github.com/kiegroup/drools/commit/8897a8dcccce10a93803d7073ecf499f3d4656ec
