Summary

This issue proposes adding infrastructure to support coverage tracking for the OpenJDK Java Style Guidelines. Similar to the existing Sun style coverage (sun_checks.xml + sun_style.xml), we would create a parallel structure for OpenJDK conventions.

Motivation

Checkstyle currently lacks a dedicated configuration and coverage documentation for the OpenJDK Java Style Guidelines (v6). This style guide is largely based on the original Sun conventions but includes a new set of rules and a some modifications. A dedicated configuration would make it easier for the community to enforce these guidelines.

Currently, Checkstyle provides:

• sun_checks.xml - Configuration for Sun Code Conventions
• google_checks.xml - Configuration for Google Java Style Guide

Adding openjdk_checks.xml would complete the coverage for major Java style guides.

Proposed Implementation

1. New Configuration File

• openjdk_checks.xml - Checkstyle configuration based on OpenJDK guidelines

2. Documentation Page

• openjdk_style.xml - Coverage documentation page showing which checks map to OpenJDK guidelines

3. Test Infrastructure

• CheckUtil.java - Add getConfigOpenJdkStyleModules() method
• XdocsPagesTest.java - Add validation for the new style
• AbstractOpenJdkModuleTestSupport.java - Base class for future integration tests
