Sorry, this does not work.
Here's my changed sample code:
----
468: ConnectFuture future = null;
469: try {
470: future = connector.connect(new InetSocketAddress(host, port));
471: future.awaitUninterruptibly();
472: } catch (Exception e){
473: throw new EstablishConnectionFailed("Can't connect due to
unresolved socket address. host="+host+" port="+port+" error:
"+e.getMessage());
474: }
----
And the exception:
----
Exception in thread "main" java.nio.channels.UnresolvedAddressException
at sun.nio.ch.Net.checkAddress(Unknown Source)
at sun.nio.ch.SocketChannelImpl.connect(Unknown Source)

at de.root1.simon.Simon.lookup(Simon.java:470) <---- This is the line in
which the exception occurs

at SampleClient.main(SampleClient.java:86)
----
As you can see: The exception is is thrown at line 470, which is the line
with the connect() call. And the exception is not caught. So it's not up to
future.awaitUninterruptibly() to throw the exception.
Maybe you forgot that this only happens in case of a network problem, as i
described in my last mail.
