There isn't any proposal to change JNI. It has never done any access checking. The only change is to -Xcheck:jni warning and logging to catch JNI code that is mutating finals. Once we dial up to have mutating finals be denied by default then we might dial up -Xcheck:jni at the same time to make it fatal.
