RFR: 8320360: ClassFile.parse: Some defect class files cause unexpected exceptions to be thrown [v2]

[Adam Sotona]

> ClassFile API throws `IndexOutOfBoundsException` when classfile structure is corrupted so the parser attempts to read beyond the classfile bounds.
> General contract is that only `IllegalArgumentException` or its subclasses is expected when parser fails.
> This patch wraps `IndexOutOfBoundsExceptions` thrown from all `ClassReaderImpl.buffer` manipulations into an  `IllegalArgumentException("Reading beyond classfile bounds", iOOBECause)`.
> Relevant tests are added.
> 
> Please review.
> 
> Thanks,
> Adam
