Description
Class-File API actually throws wide variety of exceptions based on the actual situation. Complete error handling code must cover `IndexOutOfBoundsException`, `IllegalStateException` and `IllegalArgumentException`.
Based on previous discussions we decided to consolidate on `IllegalArgumentException` with possible sub-classes.
It allows easy common error handling in majority of use case, however it allows also to distinguish source of the error when needed (for example `javap` needs to know if the exception comes from constant poll or not).
Newly introduced `ConstantPoolException` will extend `IllegalArgumentException` to indicate the source of the problem is in constant pool.
More sub-classes of `IllegalArgumentException` may be introduced later as needed and without disruption of the existing error handlers.
