ActivityCompat.requestPermissions : Can only use lower 8 bits for requestCode

So, my latest got'cha is that ActivityCompat.requestPermissions forces you to use a value between 0 and 255. The android developers are playing tricks with the result code, thus restricting you to this range. Now, it would be nice if this was documented in the online ActivityCompat documentation, since this is going to be rarely hit in testing.

Documenting the findings for future reference:
The following are code from android.support.v4.app.FragmentActivity

 /**
 * Modifies the standard behavior to allow results to be delivered to fragments.
 * This imposes a restriction that requestCode be <= 0xffff.
 */
@Override
public void startActivityForResult(Intent intent, int requestCode) {
    if (requestCode != -1 && (requestCode&0xffff0000) != 0) {
        throw new IllegalArgumentException("Can only use lower 16 bits for requestCode");
    }
    super.startActivityForResult(intent, requestCode);
}

@Override
public final void validateRequestPermissionsRequestCode(int requestCode) {
    // We use 8 bits of the request code to encode the fragment id when
    // requesting permissions from a fragment. Hence, requestPermissions()
    // should validate the code against that but we cannot override it as
    // we can not then call super and also the ActivityCompat would call
    // back to this override. To handle this we use dependency inversion
    // where we are the validator of request codes when requesting
    // permissions in ActivityCompat.
    if (mRequestedPermissionsFromFragment) {
        mRequestedPermissionsFromFragment = false;
    } else if ((requestCode & 0xffffff00) != 0) {
        throw new IllegalArgumentException("Can only use lower 8 bits for requestCode");
    }
}

RANGE
startActivityForResult() in FragmentActivity requires the requestCode to be of 16 bits, meaning the range is from 0 to 65535.
Also, validateRequestPermissionsRequestCode in FragmentActivity requires requestCode to be of 8 bits, meaning the range is from 0 to 255.
