Looking through the whole JDK codebase, most calls of ByteOrder.nativeOrder() is to check if the underlying platform is little-endian/big-endian(e.g. #4596 ). There is no reason to only provide ByteOrder.nativeOrder while leaving big-endian/little-endian checking methods blank.

If this is accepted as a new enhancement, it will need a CSR.

Personally, I don't see enough justification for such a convenience method, but this isn't my area, so my opinion doesn't carry any weight.
