February 2025 — geotools/geotools: Delivered two reliability and concurrency improvements with direct business impact. Unified ServiceException handling for WFS and WMTS improves error reporting and client feedback. Thread-safe caching in FeatureTypeRegistry (replacing HashMap with ConcurrentHashMap) enhances concurrency, reducing contention and risk of race conditions. Added concurrency testing to guard against regressions. These changes increase API robustness, reliability under load, and overall system stability.
