--------------------------------------

             Summary: java.lang.ClassCastException: org.drools.facttemplates.FactTemplateObjectType cannot be cast to org.drools.base.ClassObjectType
                 Key: JBRULES-3523
                 URL: https://issues.jboss.org/browse/JBRULES-3523
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
            Reporter: Viswa Repalle
            Assignee: Mark Proctor


I have analyzed the issue and found that the issue is happening at the initDeclaredMask method of BetaNode.java of drools-core-5.4.0.final.jar at the following lines of code:

            ObjectType objectType = pattern.getObjectType();

            if ( !(objectType instanceof ClassObjectType) ) {
                // InitialFact has no type declaration and cannot be property specific
                // Only ClassObjectType can use property specific
                rightDeclaredMask = Long.MAX_VALUE;
            }

            Class objectClass = ((ClassObjectType) objectType).getClassType();
The above code will throw ClassCastException as irrespective of the objectType is instance of ClassObjectType or not, trying to type cast to ClassObjectType.
