Unable to create process image in Process Designer, causing "(null: -1, -1): Premature end of file" message on server log

Solution Unverified - Updated -

Issue

  • I am trying to create process image in Process Designer by clicking on the PNG button. But, I am not able to see any process image under Other assets, documentation section of the respective package.
    And that is the reason why it still complains could not find process image if I run a validation on the process. However, I am able to build the package from BRM and I can even see a valid processes from business-central console.
    The same problem occurs even if I create new package and a new BPMN2 process inside it.
  • On the server console I can see the following ERROR messages:
INFO  [STDOUT] (http-0.0.0.0-8080-3) (null: -1, -1): Premature end of file.
ERROR [org.drools.guvnor.server.contenthandler.BPMN2ProcessHandler] (http-0.0.0.0-8080-3) Premature end of file.

Environment
