>          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

> 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"
