Error description

  • Error Message: Crash in JVM when class redefinition happens.
    .
    Stack Trace:
    .
    Note this can affect all platforms.
    

Local fix

  • -Xjit:disableNextGenHCR. Note however that this will cause
    throughput performance drop of around 3% depending on the actual
    application
    

Problem summary

  • The problem is caused when class redefinition happens and
    execution of compiled code transit to interpreter at bytecode
    for invoking a function call. The compiled code would pass
    incorrect arguments to the interpreter due to wrong book
    keeping.
    

Problem conclusion

  • The JIT compiler has been updated to pass correct arguments when
    transit to interpreter at invoke bytecode.
    .
