[MVT] hotspot crash

[Remi Forax]

oops,
i'm doing some modifications to my bytecode rewriter, so the generated code has a good chance to be generate an invalid class, but the VM should not crash.

To reproduce download the jar here:
  http://www-igm.univ-mlv.fr/~forax/tmp/mvt/

and run 
  java -XX:+EnableMVT -cp test-valuetypified.jar fr.umlv.valuetypify.test.InternalTest

cheers,
Rémi
