[Bug libgcj/21941] New: NPE in Socket.connect()

["tromey at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I get a NullPointerException in Socket.connect().
This seems to happen when the nameserver is not available.
My current test case is with gcjappletviewer; I can reproduce it
by stopping my VPN but leaving my /etc/resolv.conf untouched
(so it tries to contact a DNS server which is not available)

(I also remember seeing NPEs from PlainSocketImpl::connect,
but I can't reproduce that presently.  These occurred when
"tmp" was NULL...)
