Kaazing fails when establishing connection

Question

i'm using kaazing javascript jms library to establish a connection in our angular/cordova hybrid app. for the first time everyting works fine. then i kill the application and try to connect again. it just hangs and nevers calls the callback after createConnection:

  var future = factory.createConnection(function () { ..//do some stuff ... })

When I set the log-level to trace

 Tracer.setTrace(true); 

I can see the following exception in chrome developer tools:

DF5963E0C7FF945789FBBD2CCD142D2F.cache.js:692 Uncaught Application Exception: com.google.gwt.core.client.JavaScriptException: (TypeError) : $wnd.Connection is not a function

Did somebody experience the same?

Thanks Angela
