After updating my CCU2 with the latest firmware 2.49.17, XML RPC does not work anymore. After the CCU2 thing changes to online in Paper UI, it takes several minutes (Fw 2.47.20 about 30 seconds) for all things to come online. But in the control panel there are no more items available.
The openhab log is filled with messages like this:

As the firmware changelog says “Eventauslieferung der Homematic IP XML-RPC Schnittstelle wurde überarbeitet” which means something like “event delivery from the XML-RPC interface was redesigned” I suppose that either the XML-RPC addon for the CCU2 or the homematic binding needs some adjustments to work with the actual and following firmwares.
