  "message": "Preserve singleton identity across Java serialization for large_enum in full runtime\n\nClasses generated by `GenerateLarge` (`option features.(pb.java).large_enum \u003d true`) in the full runtime implement `java.io.Serializable` to emulate standard Java `enum` types, but previously omitted `readResolve()`. As a result, deserializing a `large_enum` value via `ObjectInputStream` allocated a new instance on the heap instead of returning the canonical constant, breaking `\u003d\u003d` reference equality.\n\n- Emit `private java.lang.Object readResolve() throws java.io.ObjectStreamException` in `GenerateLarge` for the full runtime (`!context-\u003eEnforceLite()`) to resolve deserialized instances via `\"UNRECOGNIZED\".equals(name)` (for `UNRECOGNIZED`, avoiding collisions with valid `-1` enum constants) and `forNumber(value)` (falling back to `UNRECOGNIZED`).\n- Add a serialization round-trip test in `LargeEnumTest` covering canonical constants, aliases, negative wire values (`-1`), and `UNRECOGNIZED`.\n\nPiperOrigin-RevId: 1012993306\n",
