IV91347: HANG DUE TO VALUEPROFILINGMUTEX LOCK NOT BEING RELREASED
Closed as program error.
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 .
This option may be avoided using the following Java option: -Xjit:disableProfiling
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.
The JIT compiler has been updated to release the ValueProfilingMutex lock when a compilation is aborted. . This APAR will be fixed in the following Java Releases: 8 SR3 FP22 (188.8.131.52) 7 SR10 (184.108.40.206) 7 R1 SR4 (220.127.116.11) 6 R1 SR8 FP40 (18.104.22.168) 6 SR16 FP40 (22.214.171.124) .
