The customer is trying to create a new version of an existing process definition on RHPAM 7.13.2 using the Business Central designer version 7.1.3.2.

They have updated version using below steps:
1) Import bpmn process( concessione-crediti-v2.6.0.bpmn) into business-central(RHPAM 7.13.2) process editor

2) Customer edits the process name, id, version and process description for creating a version 3.2.0.

3) The customer downloads the modified process definition (with no other changes) and used in the springboot project by generating kjar.

But kjar deployment is failing with NPE:

Customer modified same BPMN file through text editor and renamed it concessione-crediti-v2.7.0.bpmn. Comparing concessione-crediti-v3.2.0.bpmn and concessione-crediti-v2.7.0.bpmn, we see only two bpmn2:boundaryEvent elements in the xml. In version 2.7.0, boundary events have the attribute cancelActivity="true" specified, while in version 3.2.0 web editors omitted these parameter . That is the reason for the NPE.Its not expected to return null by element.getAttributeNode("cancelActivity") when the attribute "cancelActivity" is not specified.
