    .
    The zOS core dump was externally triggered via the zOS console,
    not by the JVM.
    

Local fix

  • Use the jdmpview 'info thread *' or 'info thread all' command to
    list all threads, then examine the thread stacks and thread
    properties to find the crashing thread.
    

Problem summary

  • The DTFJ API used by the jdmpview tool was relying on JVM data
    to identify the crashing thread. For dumps triggered externally
    it needs to use native thread data instead.
    

Problem conclusion

  • The DTFJ API used by the jdmpview tool has been updated to  use
    native thread data to identify the crashing thread in cases
    where the dump was triggered externally.
