hello Kris, 

Thank you for your reply. That helps. 

I also want to know if I borrow the same algorithm/code in hotspot/src/share/vm/classfile/verifier.[hpp|cpp] to implement the same feature in Jikes RVM will there be any copyright issue ? 

More information under "Bytecode verifier" at,

Thank you.
