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
