  Can you provide a self contained test that shows the problem and open a
JIRA with it?
  I will take a look in it.

  There is no requirement to define equals/hashcode, but if you do so, you
need to make them time consistent, i.e., they cannot change during the time
the object is asserted into the working memory or you may have problems (as
hashcode and equals behaviors are defined as kind of "identity" of the
object).

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.
