Pardon me for being dense (I'm good at it, however, and I've learned to 
play to my strengths)...  I don't understand what you are saying in the 
message above.

You say "I have not been able to reproduce any corrupt files."  Does that
mean that you believe the problem is resolved?  I am not sure where the
problem existed (you code, our code, the JVM, the compiled bytecode).  
Any clues?
