@holgerfriedrich My Fronius Wattpilot Binding is using my wattpilot4j library that is using Gson 2.11.0. wattpilot4j is deployed as OSGi bundle.
Do I now need to update it or will it run fine when requiring Gson 2.11.0?

@florian-h05 I don't remember any issues we had before when updating xtext libraries. I did this a few times before... But maybe we were just lucky.

I will need to have a look at add-ons later today. Currently build of the combined PR (all changes merged today) fails with a strange error.

The Xtext upgrade doesn’t matter, if anything is causing trouble for me, then the Gson upgrade.
I will see in the next snapshots.

This upgrade seems to have broken the LSP service. The logs of a full distro start show something like this:

14:00:14.142 [ERROR] [b.core.model.lsp.internal.ModelServer] - bundle org.openhab.core.model.lsp:5.1.0.202508311151 (202)[org.openhab.core.model.lsp.internal.ModelServer(222)] : Error during instantiation of the implementation object java.lang.reflect.InvocationTargetException: null

@florian-h05 IIRC gson upgrades are done together with xtext... this is why I mentioned it.
