Mark,
The object being retracted currently has no hashcode and equals, therefore
defaulting to the ones on Object. The reason I'm even retracting the object
is so that I can assert it again to work around bug
http://jira.jboss.com/jira/browse/JBRULES-614. Therefore the reason I am
retracting the object is because it has changed.
Is there a requirement to implement hashcode and equals? If so, does it
have to be based on all fields of the pojo? My intent was to implement
hashcode and equals, but only base them on the id fields of the class.

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?

Is there something I could be doing wrong? Is this a known bug?
