Closed as program error.
Error Message: A SIGSEGV/GPF is raised by the Java JIT run-time library code that manages code caches. This crash only occurs if the JVM is running on a 64-bit x86-based processor. . Stack Trace: TR_MCCCodeCache::replaceTrampoline TR_MCCManager::replaceTrampoline mcc_replaceTrampoline amd64CodePatching TR_MCCCodeCache::patchTrampoline TR_MCCCodeCache::patchCallPoint mcc_callPointPatching_unwrapper jitCallCFunction mergedStaticGlueCallFixer .
On x86-64, if a JIT-compiled method calls an interpreted method, the JIT compiler generates a special data structure in the current code cache. If another code cache becomes current before the compilation has completed, the data structure in the original current code cache becomes obsolete, and future searches for this data structure in the current code cache will fail, which will cause the JVM to crash.
This defect will be fixed in: 7.0.0 SR3 6.0.1 SR4 5.0.0 SR15 . The JIT compiler has been modified to re-reserve space for a new data structure for the interpreter dispatch if it detects that the current code cache has been switched.
