Class file java/net/PlainSocketImpl.java on line 251 "requires" the returned
version of the SOCKS server to equal "0". Here is a reply from an engineer at
HP who wrote HP's SOCKS code:

-Ah, you've discovered the problem that finally caused me to I give up
-and changed the socks server... IIRC, the v3 protocol sent back '3'
-as the first byte, and RFC1928 clearly makes v5 respond with '5' for the
-first byte. The NEC (or was it Aventail) site documents the first byte
-of the response to be '0' (apparently for a 'version 0 reply', or some
-such thing.) The Java lib implements that, and is very strict in what
-it will accept, violating good network programming practices.

HP had to change their code to comply to the hard coded value in the JDK. I
personally think you need a new check, or remove the current one, or give users
the opportunity to set the value without having to change Operating System code
that we have no access to.
