Have you correctly implemented your equals and hashcode? Have you made
sure that the objects fields haven't changed between the assert and the
retract?<br>

Using version 3.0.6 of jboss rules, while retracting an object, I get
the following:<br>
<br>
java.lang.NullPointerException<br>

<br>
Is there something I could be doing wrong? Is this a known bug?<br>
<br>
Thanks,<br>
