    jBPM 5.2 : NullpointerException Issue in loading knowledgeAgent.applyChangeSet(ResourceFactory.newUrlResource(url));

      Getting NullpointerException issue in JBPM 5.2 when loading kbase using KnowledgeAgent. But same is working with JBPM 5.1 without any issue.

       

      url= http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/SDS/LATEST/ChangeSet.xml 

      knowledgeAgent .applyChangeSet(ResourceFactory.newUrlResource(url)); 

       

      The following exception I am getting with JBPM 5.2 jars. But the same is working with jBPM 5.1 jars.

       

       

      Stacktrace:

      java.lang.NullPointerException
