Check the validity of a .class file

[Tom Rodriguez]

I believe the ASM framework has a verifier as part of it's toolchain.   
I don't know how good it is in terms complaining about exactly the  
same things the JVM would but at a minimum it seems like it would be  
able to sanity check the bytecodes.
