It's not unexpected or incorrect, but may be suboptimal.

This host is obviously your DNS host, and the GCJ runtime is apparently 
attempting to resolve your true host name from the DNS server using your 
IP address.

The Java runtime insists that InetAddress.getLocalHost() return your 
true IP address, not "127.0.0.1". Unfortunately, in a dialup setup with 
automatic connection, such a lookup will trigger your dialer.

The "real" Java runtime has put in some workarounds to prevent such a 
lookup unless it's really needed (i.e. you use a networking class of 
some sort, or some other class that needs the "real" hostname and IP 
address). Perhaps the Gnu java runtime doesn't have such tweaks in it..
