java is a required dependency

[chiptus]

Description of the bug

I couldn't run this without installing java first. It wasn't expected.

Probably should add it to the readme

Steps to reproduce

try to run it on a computer without java

Expected behavior

• dependency on java should be written in installation notes
• maybe we can remove the dependency?
