NPE when moving/resizing figures in OMG examples
------------------------------------------------

                 Key: JBPM-3119
                 URL: https://issues.jboss.org/browse/JBPM-3119
             Project: jBPM
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Eclipse
         Environment: Windows-7 (all?)
            Reporter: Robert (Bob) Brodt
            Assignee: Kris Verlaenen
             Fix For: jBPM 5.x

All of the example files I've tried from the OMG examples throw an
IllegalStateException followed with an NPE when moving or resizing any of the objects.
