[rules-users] ClassCastException when debugging as a drools unit test with a ruleflow

[Kris Verlaenen]

That is strange ... Only thing I can image is that you are using the 
internal drools jars that are shipped as part of the eclipse plugin in the 
Drools JUnit case and not in the normal JUnit case.  Could you try updating 
to the latest snapshot version of the Eclipse plugin (this will update your 
internal Drools jars)?
