[rules-users] KnowledgeAgent exception while migrating from 5.4 CR1 to 5.4 final

Tue May 22 12:21:12 EDT 2012

Hi,
   I've a drools application running on drools 5.4 cr1. It was working fine
until I migrated to 5.4 final. Now When I try to get the
StatefulKnowledgeSession from the Guvnor(5.4 final) I get the following
exception

However, when I replace the drools-core-5.4 final jar with
drools-core-5.4-CR1 jar (just the one jar, leaving the remaining jars as it
is) everything works fine again. Any idea If I'm missing something here?
I'm using
1>  Drools-guvnor 5.4 final
2> Drools Expert 5.4 Final
3> jbpm 5.3 final

Any help is much appreciated.Thanks in Advance.
