Additional Information

✶ Insight ──────────────────────────────────────────────
Java Version Decision:

Options:

1. Java 21 LTS (Long Term Support until 2031)

• ✅ More stable and mature
• ✅ Better library support
• ✅ It is an official LTS

1. Java 25 (Non-LTS, released March 2025)

• ⚠️ Not LTS (support until September 2025)
• ⚠️ Next LTS is Java 26 (September 2026)
• ✅ New features

Recommendation for shared libraries:
Use Java 21 because:

• Libraries must be compatible with all services
• Java 21 is the common denominator
• Services running Java 25 can use libraries compiled in Java 21
