> I'm getting a NPE exception when using drools-persistence-jpa with Drools Flow (I'm working with the trunk version 28274).  It occurs in MarshallerReaderContext and seems to be a result of JBRULES-2149.  When loading a WorkItemInfo from the database a MarshallerReaderContext is created without the ruleBase set, however the MarshallerReaderContext expects the ruleBase to be set.
> In the attached patch I have added a null check and call the super method if it is not set.  This seems to be working correctly and would have been the behaviour before JBRULES-2149.
