Error description

  • After you migrate business process definition (BPD) instances to
    IBM Business Process Manager (BPM) V8.5.5, you might receive a
    NullPointerException when you terminate one of those instances.
    The following stack trace is a typical example of what you might
    see:

    CWTBG0025E: Unexpected failure occurred while performing the
    'terminate' action.  The reported failure is: 'ä1ü':

Local fix

Problem summary

  • The problem occurs when a BPD instance is terminated and its
    correlation information should be cleared but isn?t. IBM BPM
    expects the correlation information to be included in the local
    symbol table, but migrated instances might not contain the
    correlation information. If a migrated instance does not contain
    the correlation information in its local symbol table, you
    receive the NullPointerException.
    

Problem conclusion

  • A fix is available for IBM BPM V8.5.5. With the fix applied, IBM
    BPM no longer expects the correlation information to be included
    in the local symbol table.
