First steps tutorial in standalone mode encounters socket exception due to uninitialized value

[lonerzzz]

Hi,

I have attempted to follow the tutorial at http://restlet.org/learn/2.0/firstSteps#part04 using the latest 2.1 code and running in standalone mode but have encountered the following exception.

Starting the internal [HTTP/1.1] server on port 8182
The server socket was closed

java.net.SocketException: Invalid argument: no further information
at sun.nio.ch.Net.setIntOption0(Native Method)
at sun.nio.ch.Net.setSocketOption(Unknown Source)

The problem appears to be because the setTrafficClass call against the Socket is being done with an inappropriate default value "0". I was trying to see where these values should originate but not having any luck and this being a tutorial, I thought I would pass on the message to be fixed instead.

I can supply an exported eclipse project if that helps.
