Summary

Remove methods thisClassPos and skipAttributeHolder from java.lang.classfile.ClassReader.

Problem

java.lang.classfile.ClassReader only purpose is to serve as a tool for reading content of a custom attribute in a user-provided AttributeMapper. It contains useful set of low-level class reading methods for user to implement a custom attribute content parser. However methods thisClassPos and skipAttributeHolder are not necessary for a custom attribute content parsing and so redundant in the API.

Solution

Remove methods thisClassPos and skipAttributeHolder from java.lang.classfile.ClassReader.

Specification

src/java.base/share/classes/java/lang/classfile/ClassReader.java: 
- int thisClassPos();
- int skipAttributeHolder(int offset);
