APAR status

  • Closed as program error.

Error description

  • Error Message: Segmentation error, or UnsatisfiedLinkError.
    .
    Stack Trace: The innermost stack frame is interpreted, and it
    belongs to a method whose name begins with
    invokeExact_thunkArchetype, declared on a subclass of
    MethodHandle in package java.lang.invoke.
    .
    

Local fix

  • This issue can be avoided by passing
    -Xjit:disableEscapeAnalysis. This option may degrade
    performance, but it can be limited to the problematic method.
    

Problem summary

  • In order to reduce the likelihood that a stack-allocated object
    will have to be moved to the heap, escape analysis devirtualizes
    calls where the object would escape. This devirtualization could
    be mistakenly applied to MethodHandle calls.
    

Problem conclusion

  • Escape analysis has been modified so that it no longer attempts
    to devirtualize MethodHandle calls.
