Interesting, I found a comment before this code saying:
        /* FIXME, HTTP Range returns 206, which HTTPConnection on MS JVM thinks
         * is a fatal error. Disable seeking for now. */
A bit of searching finds:
http://www.velocityreviews.com/forums/t131872-urlconnections-under-ms-jvm-cant-handle-http-206-a.html

So it looks like at least some of the MS JVMs will not be able to do
range requests, and this is how seeking is done (eg, requests a
particular section of the video).
It might be possible that newer versions of the MS JVMs have fixed
that bug, and that we could relax that check.

That one's fine, the failure is handled properly.
