I am currently trying to display a map (using OpenStreetMapLayer) and nothing shows up but the esri logo and the OpenStreetMap copyright. I am not getting any error message even if the event mapReady never occurs.
I am running the application on a distant server (via Remote Desktop) on Windows Server 2008 R2 Enterprise (SP1) and using the jre 1.7.0_25 x86. Although the SDK version is 10.1.1, an ArcGIS 10.2 application is installed on the server (ArcMap and others).
Another strange thing is that even the SDK samples seem to encounter the same issue when run in the same conditions (I cannot try on another PC). See the screenshot below:
I have been searching the web for two days but found nothing and, as there are no error messages, I ran out of ideas to google.
