[drools-dev] Fixed?? Drools core 3.0.4 - Drools does not remove itself as a listener when Facts are Retracted

Title: Fixed?? Drools core 3.0.4 - Drools does not remove itself as a listener when Facts are Retracted

We are asserting facts that support property change listeners and found that Drools added itself as a listener just fine but failed to remove itself when the facts were retracted.

We have fixed the stated problem by modifying org.drools.common.AbstractWorkingMemory as follows:

Starting at line number 582:
protected void removePropertyChangeListener(final FactHandle handle) throws NoSuchFactObjectException {
        Object object = null;
        try {
            object = getObject( handle );

            final Method method = object.getClass().getMethod( "removePropertyChangeListener",
                                                              AbstractWorkingMemory.ADD_REMOVE_PROPERTY_CHANGE_LISTENER_ARG_TYPES );

            method.invoke( object,
                          this.addRemovePropertyChangeListenerArgs );
