APAR status

  • Closed as program error.

Error description

  • Error Message: SIGSEGV/GPF is received when a user is debugging
    a Java application and attempts to step across or through an
    invokedynamic bytecode.
    .
    Stack Trace: crash originating in JIT module
    .
    The failure may be highly intermittent as failure requires the
    method being debugged to have been compiled by the JIT and for
    execution to transition back to the interpreter during or
    immediately following the execution of an invokedynamic
    bytecode.
    

Local fix

  • The problem can be worked around by using the -Xjit:exclude={}
    and dontInline={} options to fully exclude any methods
    containing the invokedynamic bytecode from being compiled by the
    JIT. The use of these options is likely to have a negative
    impact on application performance.
    

Problem summary

  • The code generated by the JIT compiler fails to marshal the
    correct operand stack values to the interpreter when
    decompilation occurs during or immediately following the
    execution of an invokedynamic bytecode.
    

Problem conclusion

  • The JIT has been modified to ensure the correct operand stack
    values are passed to the interpreter upon decompilation so that
    execution proceeds normally.
