`ByteOrder.nativeOrder()`  is already used for the BE/LE checks across the JDK, see
https://github.com/search?q=repo%3Aopenjdk%2Fjdk++%22ByteOrder.nativeOrder%28%29+%3D%3D%22&type=code

(maybe we should also have something like `public static boolean ByteOrder.isLittleEndian() `/  `public static boolean ByteOrder.isBigEndian()`  to shorten those checks a bit, but this is out of the scope of this PR)
