The beta 1 release of ArcGIS Runtime SDK for Java (Windows) is now available to download along with beta 1 for Desktop and Server. We need your feedback as this is a new product and we want to get it right.
The only beta release of ArcGIS Runtime SDK seen in the beta community site is the ArcGIS Runtime SDK for Windows Store apps Beta. The latest ArcGIS Runtime SDK for Java is 10.1.1, which is not beta. I just checked my customer care portal and there's nothing new.
ArcGIS Runtime SDK for Java 10.1.1 is the current and latest release of the software. The 3 Runtime betas that are there on http://betacommunity.esri.com today are for Qt, OS X and Windows Store. The reason these have betas is because these are "new" products. There are no current plans to provide 10.2 Betas for the existing SDKs.
To get the current software, just log on to http://customers.esri.com with your EDN subscription credentials and you should see the download links from there.
