[rules-users] Unexpected, Unclear, Unperiodic error

I have a piece of code which builds the kbase, when i run it from my local system as a java application with guvnor deployed, the code works fine. When i try and access from the admin module, it calls the same method readKnowledgeBase(), it works. But, when i call the same piece of code (the same method readKnowledgeBase()) from user module, no extra parameter, the same changeset is being used, it throws the following exception. java.lang.RuntimeException: KnowledgeAgent exception while trying to deserialize KnowledgeDefinitionsPackage at
