Thank you for contacting us.
As you mentioned, Java support is no longer supported in the latest SDK release. You can see here http://www.intel.com/content/www/us/en/support/emerging-technologies/intel-realsense-technology/000023222.html that, as of now, there’s no intention to reactivate Java support on future releases. As an alternative to Java, you can use C++ or C#. You can see several sample codes here https://software.intel.com/en-us/RealSense/Get-Started .
