Failed to run EvoSuite on Java 17

[isadoracardosozup]

I am trying to run EvoSuite in a Java 17 project, but it is not working since, currently, EvoSuite only supports Java up to 11. Has anyone had success running EvoSuite in Java 17? How much effort do we need to make EvoSuite work on Java 17?

Below, you can see the EvoSuite response when trying to run in Java 17 project:

* Error while initializing target class: **class** has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0

Hi, we have a version of Evosuite running on Java 17. It is in a private repo but we would be happy to share it once we remove some details we cannot disclose.
