      There is a workaround we implemented for this version in particular, where if the check if the process instance exists or not on a command object, the problem dissapears. You can find the problem reproduced in the attached project (persistence-issue-on-6.0.1.Final.zip). The problem can be reproduced in one of the tests, and a workaround is found in the other.

    Description

      This issue is intermitent. However, on a moderately quick processor, it happens at least once within 1000 process instances.
      The issue presents itself in version 6.0.1.Final but not in 6.1.0.Final. It happens when a ProcessInstance object is referenced before invoking the signalEvent on a specific process instance.

      Any clarification on the reasons for this problem would be appreciated. As for suggested fixes, I would recommend moving to version 6.1.0.Final. I'm reporting it so that others with similar problems can try a workaround
