# Prepare to Restrict JNI

Use for **Prepare to Restrict JNI** work from [JEP 472](https://openjdk.org/jeps/472) when targeting JDK 24+.

## When active

- Add `--enable-native-access=...` for modules/classpath code that loads or links native code.
- Test with `--illegal-native-access=deny`.
- Inventory JNI with `jnativescan` and native library loads with JFR.

## Pitfalls

- `ALL-UNNAMED` grants all classpath code; prefer modules for narrow grants.
- Library code cannot silently grant itself native access.
- FFM and JNI restriction policy are aligned in JDK 24+.

## Examples

Read `examples/jep-472.md` for JEP-derived snippets.
