Windows Desktop Application in container

[NewbieProger]

Hi. I'm AQA and I need to test java desktop application via UI tests on java

1. App on java which runs via java -jar directly, so it's suposed that it's crossplathorm
2. This application requires graphical interface. As I checked in the internet, I can use x11
   The main idea:
3. I build container with app on java
4. add container with graphical interface
5. build jar with tests
6. combine container in one internal network between containers
7. run
   Main problem that we run like now just on VM or any PC - driver from UI testing steals mouse and keyboard. Also we can't do a parallel testing cos if this issue and cos of display resolution
   Will it resolve this issue? Help me with your ideas please
