This doesn't work on windows either:
> ERROR: 2021/10/19 22:43:31.224452 Error:Create Object failed. Could not create JHMachine: <Class not registered>
> ERROR: 2021/10/19 22:43:31.224452 Module[Main] - Could not get IJHMachine : Create Object failed. <Class not registered>

It's been some time since I tested, what am I missing?

Still can't reproduce the issue with the current program, also fails on
Windows.
