NIO is not present before JDK 1.4. The JDBC driver, at least, needs to
support earlier JVMs.

That's no use if you don't know the endianness of the data you're
receiving (which is what happens under <= 7.3 -- the data followed the
server's byte ordering)
The problem with using native byte orderings is not the byte ordering
itself, but that the order is unpredictable -- at best, you have to
implement code to handle both orders, and at worst you have to just take
a guess and hope you were right..
