[Adam Sotona]

> Classfile API class hierarchy makes assumptions when class is not resolved and that may lead to silent generation of invalid stack maps. Only debug-level log information of case is actually provided.
> 
> Proposed patch throws IllegalArgumentException when the class is not resolved instead.
> 
> Thanks for review.
