Why does appengine try to use Super Dev Mode?
=============================================

Every time I deploy my GWT app to appengine and try to access it I get the white loading screen, then after about 20-30 seconds I get this message:

![Couldn't load project from Super Dev Mode server at appspot.com:9876. Please make sure the server is ready. Do you want to try again?](https://i.stack.imgur.com/2L11P.png)

I use maven with the [gwt-maven-plugin](http://mojo.codehaus.org/gwt-maven-plugin/) and [appengine-maven-plugin](https://code.google.com/p/appengine-maven-plugin/). Deploying using the [maven-gae-plugin](https://github.com/maven-gae-plugin/maven-gae-plugin) gives the same results.

If I switch back to using 2.6.1 versions of gwt and the gwt-maven-plugin it deploys ok, so it would seem it's something to do with the automatic dev mode launcher.
