Continously updating facts and firing rules leads to OutOfMemoryException
-------------------------------------------------------------------------

                 Key: JBRULES-847
                 URL: http://jira.jboss.com/jira/browse/JBRULES-847
             Project: JBoss Rules
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Reteoo
    Affects Versions: 3.0.5
         Environment: Linux, Eclipse 3.2, JDK 1.6, JBoss Rules from Maven rep
            Reporter: Lars Ivar Igesund
         Assigned To: Mark Proctor


The rules at the end are checked against two facts of type TextileUser. The facts are true for the first rule  when asserted. The action modfies the facts to make them true for the other rule, which again make the facts true for the first rule, creating an infinite loop.

On my setup, this leads to an OutOfMemoryException after about 40 seconds. Increasing the number of facts to 100 didn't change this.

--------------------

rule "User needs textiles"
 
        when
                #conditions
                tu: TextileUser(wantTextile==true)
        then 
                #actions
                tu.collectTextiles();
                modify( tu );
 
end
 
rule "User has dirty textiles"
        #include attributes such as "salience" here...
        when
                #conditions
                tu: TextileUser(hasDirtyTextiles == true);
        then 
                #actions
                tu.returnTextiles();
                modify ( tu );
end
