Java 23 support

[danischroeter]

It would be nice to get java 23 supported - but this will require a new version of kanela see kamon-io/kanela#163

Just saw @hughsimpson kamon-io/kanela#161 should allow easier version upgrades - any hint on how to use this?

@danischroeter That whole approach turned out not to work because of github permission reasons that I was never able to fully debug> I think @ivantopo is pretty close to getting us into a much nicer world with kanela where this won't bite so hard, but it's not there yet afaik

Jep thx for the update!
Comming along nicely...

What about Java 25 (current LTS)?

After migrating to Java 25 we start observing following warning:
