APAR status

• Closed as program error.

Error description

  .
  

Local fix

Problem summary

• The problem is caused when a thread is attached as daemon from
  JNI code using API AttachCurrentThreadAsDaemon(). JVM doesn't
  retain the daemon status of the thread. This leads to a graceful
  shutdown of the JVM owing to the validation of a count that
  reflects the non dameon status from within the JVM
  

Problem conclusion

• This defect will be fixed in:
  1.4.2 SR13 FP6
  .
  JVM has been updated to retain the daemon status of the thread
  attached as daemon from JNI thereby preventing premature
  shutdown of JVM.
  .
  .
  To obtain the fix:
  Install build 20100822 or later
  

Temporary fix
