The actual command I ran was:
/usr/local/sablevm/bin/sablevm-debug -p "sablevm.verbose.methods=true" \
  Hello 2>&1 | tail -5000 > output-methods.txt

/usr/local/sablevm/bin/sablevm-debug -p "sablevm.verbose.methods=true" \
  -p "sablevm.verbose.instructions=true" Hello 2>&1 | tail -10000 >
output-instructions.txt

I didn't have time to recompile and do the next steps but from the
output I suspect the following piece of code in java.io.FileInputStream:

    public
    FileInputStream(FileDescriptor fd) throws SecurityException
    {  
      // Hmmm, no other exception but this one to throw, but if the
    descriptor
      // isn't valid, we surely don't have "permission" to read from it.
      if (!fd.valid())
        throw new SecurityException("Invalid FileDescriptor");
    

Does that make sense to you? Hopefully I can send more data later.
(But it might not be till tomorrow).

Cheers,

Mark
