IV78431: JVM CRASHES IN THE JIT COMPILER
Closed as program error.
Error Message: A segmentation error is raised by the JIT compiler with vmstate=0x51eff. . Stack Trace: N/A . This problem is known to be very intermittent
The JVM option -Xjit:disablePRE may be sufficient to stop the failure from occurring in some cases. This option is known to have a moderate impact on the performance of some workloads. No workaround is known to be completely effective at preventing all occurrences of this failure.
The problem was caused by a JVM runtime compiler optimization incorrectly handling one of the runtime safety checks of the Java programming language. The resolution check verifies that a symbolic class name resolves to a particular class that the JVM can identify. An internal JIT data structure associated with this check could be modified to an incorrect state, resulting in the crash.
The problematic optimization was corrected to ensure that this runtime safety check is correctly handled. . This APAR will be fixed in the following Java Releases: 8 SR2 (184.108.40.206) 7 SR9 FP20 (220.127.116.11) 7 R1 SR3 FP20 (18.104.22.168) 6 R1 SR8 FP15 (22.214.171.124) 6 SR16 FP15 (126.96.36.199) .
