Error description

  • When one federated system is not reachable, the Process
    Federation Server REST API might return an HTTP 500 error and
    multiple FFDC
    log entries related to NullPointerExceptions, similar to the
    following examples, might be generated in the Process Federation
    Server logs/ffdc directory:
    
    Exception = java.lang.NullPointerException
    Source =
    com.ibm.bpm.federated.query.rest.impl.SystemStatusThread
    probeid = 1007

Local fix

Problem summary

  • No additional information is available.
    

Problem conclusion

  • A fix will be available in IBM BPM V8.5.7 cumulative fix 2017.03
     that prevents the Process Federation Server retriever component
     from throwing NullPointerExceptions when a federated system is
    not reachable. With the fix applied, the Process Federation
    Server REST APIs no longer returns an HTTP 500. As expected the
    API returns the consolidated data it obtained from the federated
     systems and indicates the system it couldn't reach.
    

Temporary fix

  • Not applicable.
