Hi

I recently upgraded my openhab2 installation from 2.0.020160906221424 to 2.0.020160923010346. Since this time I get the following exception on every usage of a Switch item:

2016-09-24 13:39:06.062 [ERROR] [ore.internal.events.OSGiEventManager] - Dispatching/filtering event for subscriber 'org.eclipse.smarthome.core.events.EventSubscriber' failed: java.lang.NoClassDefFoundError: org/openhab/core/library/types/OnOffType
java.util.concurrent.ExecutionException: java.lang.NoClassDefFoundError: org/openhab/core/library/types/OnOffType
    at java.util.concurrent.FutureTask.report(FutureTask.java:122)[:1.8.0_101]
...

I use the openhab2-online package on a raspberry 2 (raspbian).
All seems to work very well but this exceptions makes me a bit nervous :)

Thanks!

Would you have a few more lines of the stacktrace, so that we can see, which code actually throws this exception? What binding do you have installed and does the message go away if you deinstall them?

[kaikreuzer]

Btw, in general you should better report such issues at https://github.com/openhab/openhab-distro/issues (unless they are clearly related to an OH1 add-on).

This is the full stacktrace. I cant see any specific binding, so I dont tried to uninstall some OH1 bindings...

(next time I will file an issue at openhab-distro :))

This is my addons.cfg

package = standard

# A comma-separated list of bindings to install (e.g. "sonos,knx,zwave")
binding = homematic,astro,exec,samsungtv,caldav-command,weather

# A comma-separated list of UIs to install (e.g. "basic,paper")
ui = basic,paper

# A comma-separated list of persistence services to install (e.g. "rrd4j,jpa")
persistence = mysql

# A comma-separated list of actions to install (e.g. "mail,pushover")
action = 

# A comma-separated list of transformation services to install (e.g. "map,jsonpath")
transformation = map,regex

# A comma-separated list of text-to-speech engines to install (e.g. "marytts,freetts")
tts = 

# A comma-separated list of miscellaneous services to install (e.g. "myopenhab")
misc = restdocs,myopenhab

I have honestly no clue on how this could happen. I would assume that this issue is due to the upgrade. Could you try wiping your userdata/cache folder to see if this makes a difference?

[otbe]

I always execute this script before upgrading:

#!/bin/bash

USER_DATA=/var/lib/openhab2
RUNTIME=/usr/share/openhab2/runtime

rm -rf $RUNTIME
rm -r $USER_DATA/tmp/*
rm -r $USER_DATA/cache/*

But I think this issue can be closed...after a restart (of the PI) the exception is gone.
