RE: Apparently-random UnknownHostException while attempting POST operation

Problem solved, I hope -- apparently IPv6 causes trouble for the Java VM -- 
this is a bug in Java, but a workaround is to put 
-Djava.net.preferIPv4Stack=true on the Java command line. It seems to have made 
the UnknownHostException go away, so I am happy!

Others have bumped into this bug; see:
http://stackoverflow.com/questions/1608503/domain-name-resolution-not-working-in-java-applications-on-ubuntu64-9-04-machine

Hope this helps,
