Upgrade project to support java 17

[jesper-beck-holm]

Hello barbelH community,
This project is unable to run with java 17. There is old libs and cglib is one of the bad guys.

Is an upgrade of this project in pipe anytime soon?

I will take a look at this one soon ...

Looked deeper into this issue. CQEngine uses Kryo to serialize/deserialize objects to SQLLite. Kryo isn't Java 17 compatible right now. There is already an issue there complaining about this fact. Unfortunately I have to whait for them to get this finished.

The master branch already uses Bytebuddy as standard proxying library. That should be enough to run barbelhisto core in JDK 17 envirnoments as long no DiskPersistence is involved as collection backup.

Version 2.2.0 using Bytebuddy should work in JDK 17 as long no DiskPersistence / SQLLite / Kryo Serialization is required. I have to wait for my dependencies to follow up on JDK 17 issues.
