I have applied my generator to the swagger petstore api, hehe it is pretty unstable, but after some NPE fixes and minor improvements I have generated the API Interface and models. Demo project here https://github.com/ibaca/petstore-client-gwt, uploaded with sourceMaps at https://ibaca.github.io/petstore-client-gwt/, ups, bud sadly github forces https but swagger petstore is not exposed in https so a mixed content exception is thrown. Just download locally and use 'mvn gwt:devmode' to try it out.
