Installed GWT today and ran through the steps in the Getting Started
guide. When I tried to debug the sample I created as a web application,
GWT was unable to create the DevAppServer:
Initializing App Engine server
Unable to start embedded HTTP server

I'm using the IBM Java 7 SDK. Why is GWT making calls directly to classes
in the sun packages and not, in this case, java.net?
