I was looking in the log file today and noticed repeated messages the same as this appearing every 10 seconds.
==> /var/log/openhab/openhab.log <==
2021-05-24 20:51:34.587 [WARN ] [nhab.core.internal.items.ItemUpdater] - NoSuchMethodException while creating Class instance: org.openhab.core.library.types.RawType.()
It didn’t used to be there and everything seems to be working as far as I can tell. I am running Openhabian on a RPi and have upgraded recently to the latest snapshot but that may be unrelated to the warning as I hadn’t checked the log file for day or two.
Any ideas? I can’t interpret the message. Many thanks.
RawType is the type used by Image Items, do you have any of those? If so, what binding(s) are they connected to? If not, what bindings do you have that supports Image Items?
This information would help with locating the cause of the problem
Sounds like a likely candidate. Before opening an issue it would be good to collect som more info though. Start by setting the binding to debug logging (log:set DEBUG org.openhab.binding.zoneminder in the karaf console) and see if there are any messages from there around the same time.
