Error description
Error Message: A SIGSEGV is received during compilation of certain methods with On-Stack Replacement (OSR) enabled in a non-default configuration. . Stack Trace: TR::forward_list<TR::CFGEdge*,TR::typed_allocator<TR::CFGEdge*,T R::Region&> >::push_front() TR::CFGEdge::createEdge(TR::CFGNode*,TR::CFGNode*,TR_Memory*,TR_ AllocationKind) OMR::CFG::addEdge(TR::CFGNode*,TR::CFGNode*,TR_AllocationKind) TR_InlinerBase::linkOSRCodeBlocks() TR_InlineCall::inlineCall(TR::TreeTop*,TR_OpaqueClassBlock*,bool ,TR_PrexArgInfo*,int) . This problem can only happen when non-published JIT compiler options or environment variables are used
Local fix
This issue can be worked around by not using the option -Xjit:enableOSROnGuardFailure when using full speed debug functionality.
Problem summary
The crash is caused by late inlining of methods when OSR is enabled. When performing OSR calculations for the feature OSR on guard failure, the incorrect call stack was used, resulting in a crash.
Problem conclusion
The JVM has been updated to prevent the crash by using the correct call stack. . This APAR will be fixed in the following Java Releases: 8 SR5 FP7 (8.0.5.7) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
