Java Concurrency Checklist

The checklist spans design patterns, documentation, synchronization, race conditions, testing, and scalability, with specific items like justifying thread safety and using @GuardedBy annotations, as detailed in the README sections.

It provides concrete checks for common pitfalls, such as avoiding nested critical sections and ensuring proper lazy initialization, referencing real-world examples like ConcurrentHashMap misuse and double-checked locking patterns.

Emphasizes integration with tools like Error Prone and IntelliJ IDEA inspections, making it easier to enforce checks in development workflows, as mentioned in items about @GuardedBy and static analysis.

Strongly advocates for documenting threading models and justifications for concurrency decisions, which is critical for maintainability, highlighted in sections like 'Documentation Guidance' and 'Rationalize'.
