I am trying to run a very simple application for the Restlet example, available here http://restlet.org/learn/guide/2.2/introduction/first-steps/first-application
I try to run the client on an Android device, but I get the following error:
Unable to convert a [application/json,UTF-8] representation into an object of class org.restlet.example.common.Contact
java.io.IOException: Unable to create the Object representation

The only way to get this application to work is to use Restlet 2.1-M4. I tried with 2.2-RC2 and even with the "stable" release 2.1.7.
I understand that the application was tested using the "Restlet Framework 2.1 Milestone 4", but it seems too strange to me that a later stable release, such as 2.1.7, is for a trivial example, such as this!
