After upgrade to OH3 (3.0.1 release) I can see WARN message during the startup process:
2021-03-08 11:09:36.588 [WARN ] [nhab.core.internal.items.ItemUpdater] - InstantiationException on org.openhab.core.library.types.RawType
And I wonder what can causing this and if it is a big problem.
Maybe someone can help me to trace the source of this warning.
I have searched on github repo openhab/openhab-addons for that string
and found that among all listed bindings I am using three of them: OpenWeatherMap, mqtt, http.
Maybe it can help somehow.
