MQTT not working after upgrade to 1.8

@watou, any chance you could help me get my contact properly updating in OH2?

This is my item, but it just doesn’t seem to update…

Contact Garage01Contact “Garage1” (AllItems, LogRRD4J) {mqtt=“<[mosquitto:homie/d406c6e0/garagesensor/open:state:open:true],<[mosquitto:homie/d406c6e0/garagesensor/open:state:closed:false]”}

This is the full detail of my struggles…
