Disable online check with DNS query

When try to use icedtea-web behind my corporate proxy I get the following
error:
java version &quot;1.6.0_24&quot;

Looking at
<a href="http://icedtea.classpath.org/hg/icedtea-web/annotate/dbc6a336b087/netx/net/sourceforge/jnlp/Launcher.java#205">http://icedtea.classpath.org/hg/icedtea-web/annotate/dbc6a336b087/netx/net/sourceforge/jnlp/Launcher.java#205</a>
I can see that icedtea-web assume that &quot;no name resolution&quot; mean &quot;offline&quot;.
It's wrong when using a proxy.

The attached patch is a workaround which work for me. If it's really necessary
to check for &quot;onlineness&quot; so early I guess it would be better to do something
like &quot;if not offlineAllowed and noDNS and noProxy then ...&quot;.</pre>
