Sorry, something went wrong.
The bug was in line 22 of TypeHandlerBase.cs: if (x != null && y != null) return false; This condition returns false when BOTH objects are non-null, which is the normal comparison case. This caused the ConcurrentDictionary to: 1. Never find existing cache entries (Equals always returns false) 2. Add a new entry for every SetValue() call 3. Grow unboundedly causing memory leaks in production The fix changes the null checks to proper equality semantics: if (x == null && y == null) return true; // Both null = equal if (x == null || y == null) return false; // One null = not equal Added unit test to verify cache reuse behavior. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
