--------------------------------------------------------------
I am trying to modify xml using the following code using Guvnor REST API. But getting the following exception. Please guide me where I am going wrong.

I am getting the proper BPMN xml (i.e content). But when doing when doing unmarshalling I am getting the exception.

WebClient client = WebClient.create(" http://127.0.0.1:8080/ http://127.0.0.1:8080/","admin", "admin", null);
String content=client.path("drools-guvnor/rest/packages/pkgName/assets/"+assetName+"/source").accept("text/plain").get(String.class);
GuidedDecisionTable52 dt = GuidedDTXMLPersistence.getInstance().unmarshal(content); *// getting exception here*
