Closed as program error.
Error Message: A SIGSEGV or ABEND occurs in a JIT-compiled method after an inlined method throws an exception which is caught by a handler in the JIT-compiled method. The catch is often implicit, caused by the exception being thrown out of a synchronize block, which requires the JVM to unlock an object before continuing to look for a suitable catch block down the call stack. Hence, in some cases, the crash point can be in the native function jitMonitorExit. . Stack Trace: . This failure only occurs on a z196 system running z/OS or z/Linux.
This issue can be avoided by using the -Xjit:disableZGryphon option.
The crash or ABEND occurs when program execution jumps to a wrong exception handler, due to an incorrectly specified exception range in the exception table of the JIT-compiled method. This problem is caused by a z196-specific optimization that exploits conditional move instructions to eliminate unnecessary branches. When the branch being eliminated comes from a basic block that can throw exceptions, the JIT compiler fails to mark the end of the exception range properly, and eventually generates a corrupt exception table.
This defect will be fixed in: 6.0.1 SR2 FP1 7.0.0 SR2 . The JIT compiler has been updated to generate correct exception ranges in this scenario.
