Stopped without executing or closing null after upgrate 4.1.4 to 4.2.2

Continuing the discussion from WARN message "Stopped without executing or closing null":

Hey,
after upgrading 4.1.3 to 4.2.2 i get the message:
"[WARN ] [e.jetty.util.thread.QueuedThreadPool] - Stopped without executing or closing null"
round about every 5-10 minutes.

Could someone help me to solve this?

You may try clearing cache with openhab-cli clean-cache.

I’ve tried clean-cache and restart, but doesn’t help.
The message still occures.

I’ve deinstalled shelly Binding, and the warning messages stopped.

After reinstalling the shelly Binding, the warn Message
Stopped without executing or closing null
comes again.

So it seems that there is a problem with the shelly binding or?

Same here. Better post your experience in the shelly thread as this is where Markus, the developer, is active.
