    .
    Stack Trace: N/A
    .

  • Specify -Xfuture to enable additional checks in the verifier.
    

Problem summary

  • JVM doesn't detect classes with extra bytes on the end unless
    -Xfuture is specified.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR1
    6.0.1 SR2
    .
    The JVM has been modified to always detect extra bytes at the
    end of class files regardless of whether -Xfuture has been
    specified.  This change was made to match the behaviour of the
    Oracle JVM
