I don't know if the property "bad_container_name" has anything to do with the problem,
I see it is something generated by Eclipse.

OK sorry for the noise, by comparing with another dev we saw that the main Class was
wrong and that was the problem. Switched from 
com.google.gwt.dev.GWTShell
to
com.google.gwt.dev.DevMode

Still don't know why it was changed to com.google.gwt.dev.GWTShell in the first place...
