An ART runtime built-in optimization for native methods to speed up JNI transitions: Methods that are annotated with @CriticalNative use the fastest available JNI transitions from managed code to the native code and back.

An ART runtime built-in optimization for native methods to speed up JNI transitions: Compared to normal native methods, native methods that are annotated with @FastNative use faster JNI transitions from managed code to the native code and back.
