I installed the GWT today and ran through the getting started document.
When I tried, Debug As Web Application, I got the following:
Unable to start embedded HTTP server

I'm using the IBM Java 7 SDK, which clearly does not have the same set of
sun packages as the Oracle SDK. Why is GWT making calls into the sun
classes instead of, in this case, java.net? The sun classes are not
intended for application use.
