Hi All, For anyone interested in experimenting with the proposed java.util.json API design, I've created a backport that works with JDK 21:
https://github.com/simbo1905/java.util.json.Java21 This is derived from the OpenJDK sandbox commit d22dc2ba (mid-July 2025). The backport: - Works with JDK 21 - Focuses on API compatibility rather than performance - Uses double-checked locking instead of StableValue - Runs the JSON Test Suite The repository includes examples showing the API in use with records, streams, and type conversions. Regards, Simon
