Tellstick binding problem


First of all, thanks a lot for the fantastic work on the Telldus integration with Openhab. It is really cool!
I have a slight problem: I installed the biding and the bridge to Telldus Live. It found all my devices and everything is basically cool. However, I get the following in the log:

2017-08-27 13:54:16.840 [ERROR] [] - Failed to update
java.lang.NullPointerException: null

This comes immediately after (re)starting OpenHab2, and afterwards, top shows java using 95-120% of CPU, and I start getting a lot of messages about delays for message transfer, e.g.:

2017-08-27 14:00:18.690 [WARN ] [] - Dispatching event to subscriber ‘org.eclipse.smarthome.core.thing.internal.ThingManager@2696fe’ takes more than 5000ms.

Any idea what could be wrong?

Thanks in advance, and apologies if this is a known problem and my search skills are not up to par.



Part of this error might be related to this:

Do you have both devices and sensors that you communicate with, or only one of them?
