A general comment: since there is native runtime code to perform conversions for constants (IIRC) I think we need to some special tests to verify that works correctly (shame there is no way to leverage the Java code in such cases). It might require some advice from other HotSpot engineers, but i think we do need to follow up with another PR on that aspect.
