Error description

  • Error Message: The number of threads reported in the 1XMPOOLINFO
    section of the javacore.txt file does not match the expected
    value.
    .
    Stack Trace: N/A
    .
    Example text from javacore:
    0SECTION       THREADS subcomponent dump routine
    NULL           =================================
    NULL
    1XMPOOLINFO    Thread pool info:
    2XMPOOLTOTAL       Current total number of threads: 15
    

Local fix

Problem summary

  • The number reported was correct but was confusing as it was the
    number of pooled threads in the JVM not the number of live Java
    threads.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR4
    6.0.1 SR5
    .
    The section has been clarified and expanded to give the number
    of pooled, live and daemon threads to make it easier to
    understand.
    Updated example text from javacore:
    0SECTION       THREADS subcomponent dump routine
    NULL           =================================
    NULL
    1XMPOOLINFO    JVM Thread pool info:
    2XMPOOLTOTAL       Current total number of pooled threads: 15
    2XMPOOLLIVE        Current total number of live threads: 4
    2XMPOOLDAEMON      Current total number of live daemon threads:
    3
