Java Binding Specification · Bindings Policy

Java Codec Artifact Policy

Java bindings do not provide JSON, Protobuf, or MessagePack codec artifacts. The core Java binding exposes raw Message and byte payload APIs only.

Applications that need framework-level serialization should use framework codec extension artifacts under framework/languages/java/, such as zlink-framework-codec-protobuf or zlink-framework-codec-msgpack. Do not add replacement codec artifacts under the Java binding tree.

This keeps the Java binding contract focused on the low-level protocol API. Codec selection, packet-name resolution, serializer lookup, and typed request/reply policy belong to the framework layer.
