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.
