Key Takeaways

  1. java.lang.StringBuilder is the most-used class (20+ calls across 6 files) — used heavily for string concatenation in HTML helpers and converters.
  2. java.util.concurrent.ConcurrentHashMap is the most-used concurrent collection (6 files) — core to caching, DI scopes, and event pooling.
  3. java.lang.System is used for stdout/stderr access, property retrieval, and thread interruption (7 files).
  4. java.time.* classes (9 unique classes) are used extensively in the async/time subsystem for modern date/time handling.
  5. HTMLHelper.cfc is the single file with the most Java interop calls (18) — all StringBuilder for HTML generation.
  6. Serialization (ObjectMarshaller.cfc) uses 4 distinct java.io classes for binary serialization.
  7. Caching stores (ConcurrentStore, ConcurrentSoftReferenceStore) rely on ConcurrentHashMap and SoftReference for eviction policies.
