The exceptions happened in our test environment after I added a bunch of new-nodes at the same time that was in a different (previously non-existing) datacenter. The datacenter is determined using GossipingPropertyFileSnitch and started repairs on a bunch of nodes at the same time using

nodetool -h <node> repair -inc -par

The nodes in the old datacenter had previously been repaired using the -inc option.
