ClassFile API dives into the nested constant pool entries without type restrictions, while parsing a class file. Validation of the entry is performed post-parsing. Specifically corrupted constant pool entry may cause infinite loop during parsing and throws SOE. This patch resolves the issue by providing specific implementations for the nested CP entries parsing, instead of sharing the common (post-checking) code. Added test simulates the situation on inner-looped method reference entry.
Please review.
