A BatchCommand triggering a rule which modifies the KBase causes a deadlock
---------------------------------------------------------------------------

                 Key: JBRULES-3274
                 URL: https://issues.jboss.org/browse/JBRULES-3274
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
            Reporter: Mario Fusco
            Assignee: Mario Fusco


Create a BatchCommand containing an insert and a fireAll. Make that inserted fact activate a rule which modifies the KBase, e.g. adding another rule on the fly.
When executing the batch command, the thread will acquire a read lock. The kBase modification will then require a write lock, causing the deadlock.
