Shame on them, then.

One should be generally aware of the major packages available for the version
of Java one is using. The older and more major the package, the less excuse
for not being aware at least of its existence and when it came in. Had the OP
even looked minimally at the first link to NIO he got, after it was "somehow
being pointed to", he'd've seen that it came in in Java 1.4. Your argument is
moot because they *were* directed to look at it!

NIO is old enough and major enough that everyone who does any I/O at all in
Java should be aware that it exists, even if they don't use it or don't have
much expertise with it. I have negligible expertise with NIO, but I read the
Sun docs on the different versions and at least knew it existed since it came out.

For those who want to know what versions of Java support what features,
there's a good summary at
<http://en.wikipedia.org/wiki/Java_version_history>
so they don't need to make excuses like "no one somehow pointed me to it" as a
response to when someone pointed them to it, or depend on apologists for
ignorance as you're playing here.
