APAR status

  • Closed as program error.

Error description

  • Error Message: N/A
    .
    Stack Trace: N/A
    .
    

Local fix

  • Problem can be worked around by using -Xjit:disableUnsafe
    

Problem summary

  • The problem is caused when one thread blocks on a variable that
    is updated by another thread which uses putOrderedInt to do so.
    Because putOrderedInt gets inlined multiple times one after
    another, it creates a race condition.
    

Problem conclusion

  • The JVM has been fixed to not inline methods multiple times
    incorrectly.
    .
