I just upgraded to OH2 build 1238. I now get these in my logs every 5 seconds. There is no other detail around them, so I have no clue how to troubleshoot this:
2018-03-23 15:03:45.703 [WARN ] [home.core.internal.items.ItemUpdater] - InstantiationException on org.eclipse.smarthome.core.library.types.QuantityType
} catch (InstantiationException e) {
logger.warn("InstantiationException on {}", e.getMessage()); // Should never happen
} catch (IllegalAccessException e) {
logger.warn("IllegalAccessException on {}", e.getMessage()); // Should never happen
Not sure why anyone would make such an assertion while trapping for the exception that can’t occur.
