Drools core multithreading issue
--------------------------------

                 Key: JBRULES-2125
                 URL: https://jira.jboss.org/jira/browse/JBRULES-2125
             Project: JBoss Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-core
    Affects Versions: 5.0.1.FINAL
         Environment: Java HotSpot v 1.6.0_06, WinXP SP3
            Reporter: Andrey Nechaev
            Assignee: Mark Proctor
         Attachments: Main.java

Attachement below is the code showing the problems. 

The program hangs and nothing is displayed in the Console.

If I put lines 10-11 before the line 6, I get a NullPointerException:

Exception in thread "main" java.lang.NullPointerException
            at org.drools.reteoo.ObjectSource.addObjectSink(ObjectSource.java:124)
...

But, if I comment out the lines 2&3, everything works ok.
