[bug] TornadoVM sketch fails for method render(null)

I think we have something broken in TornadoVM. The project seems to have been tested with v1.0.4.

I tried the small refactoring change that we did in the TornadoBackend class (getDeviceCount -> getBackendCounter) in this branch. It now builds, but it throws a compilation error in the sketcher:
