APAR status

  • Closed as program error.

Error description

  • Error Message: Application threads are waiting on the
ValueProfilingMutex lock to be released by a JIT compiler thread
causing the application to hang. This can be seen in the
javacore*.txt generated by the JVM's dump agent.
.
Stack Trace: N/A
.

Local fix

  • This option may be avoided using the following Java option:
-Xjit:disableProfiling

Problem summary

  • The JIT compiler threads will acquire and release the
ValueProfilingMutex lock during compilation. The lock is also
used by application threads as part of application profiling by
the JIT compiler. It is possible for a compilation to abort due
to it exceeding thresholds. In some scenarios, the
ValueProfilingMutex lock was not being released when a
compilation thread that acquired it aborted the compilation
causing the lock to be held by that thread indefinitely. If this
happens, then application threads wanting to acquire that lock
as part of profiling will endlessly wait to acquire this lock
causing the application to hang.

Problem conclusion

  • The JIT compiler has been updated to release the
ValueProfilingMutex lock when a compilation is aborted.
