Error in the Java Standard Library while using Tor sock proxy

I'm using a Java program as a network client on TOR. It uses the
standard Java support for SOCKS. I'm currently using the SOCKS4
protocol, but I've gotten the same error while using 4, 4a, and 5. The
stack trace looks something like this:
Caused by: java.net.SocketException: Reply from SOCKS server contains
wrong code
at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:401)
I googled this error message and found someone had put up the source
code to the JDK uncompressed and browseable on the web (how useful!
Wish Sun would do that themselves and let google at it).
http://www.cs.umb.edu/~bill/java/jdk1.4/src/java/net/SocksSocketImpl.java
You searching on that page you can find where it happens, it's right
after it contacts the SOCKS server for the first time and it's reading
the response from the server. It's expecting a int that will signify a
IPv4 (1) or IPv6 (3) connect request, a DNS lookup request (2), and the
TOR socks server seems to be returning something that it's not
expecting. (Wouldn't have been nice if that error message told us what
it got that it didn't expect?)
Any ideas?
Thanks,
