Local fix

  • -Xjit:disableRedundantMonitorElimination
    

Problem summary

  • The JIT made an incorrect assumption about its own internal
    representation of Java static string constants, erroneously
    interpreting one as a static field instead.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR1
    6.0.1 SR2
    .
    The JIT has been fixed to ensure that it is dealing with a
    static field, not a static string constant.
