Does SikuliLibrary Support Window Server 2016 64bit?

Nobody has claimed this yet.

Dear Wang Yang,

I am using Sikuli 1.1.3 with jython 2.7.1, Robot Framework 3.1.2 and jre-8u131-windows-x64 on Windows Server 2016 64bit (virtual machine).

Also using robotframework-SikuliLibrary 1.0.8 to enable the RobotFramework and Sikuli integration.

Quick question:

Does SikuliLibrary support Window Server 2016 64bit in the virtual environment?

I have been using above setup on the Windows 10 64bit machine and it works perfectly fine. But same setup doesn't seems to work on Windows Server 2016. Appreciate if you could shed some light on potential root cause or any particular workaround which could help me to move on.

FYR, exceptions encountered on the server during test execution:

Start with the reported failure in SikuliLibrary/sikuli.py, especially _start_sikuli_java_process, and trace the subprocess call into Robot Framework's robot/libraries/Process.py. Compare the Windows 10 and Windows Server 2016 environments using the stated Sikuli, Jython, Java and Robot Framework versions. Done means identifying a reproducible cause and documenting supported configuration or a verified workaround.
