APAR status

  • Closed as program error.

Error description

  • Error Message: N/A
    .
    Stack Trace: N/A
    .
    When large numbers of JVMs terminate simultaneously the thread
    "Attach API wait loop" may not terminate cleanly when the JVM
    exits.
    In this case the JVM kills the thread and the JNI function
    DestroyJavaVM() returns JNI_ERR.
    

Local fix

  • disable attach API by setting the "com.ibm.tools.attach.enable"
    system property to "no".
    

Problem summary

  • The attach API cannot shut down due to contention with other
    JVMs for access to attach API files.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR1
    6.0.1 SR2
    .
    The JVM was updated to retry in the case of contention.
    

Temporary fix
