Description

In a 3 node cluster with one seed on trunk, a member on trunk, and another member on a previous version, the following occurs only on the non-seed trunk member:

ERROR 16:44:18,708 Exception in thread Thread[GossipStage:1,5,main]

This doesn't repro if a non-trunk member is the seed, however upgrading the seed first should still be valid.

• relates to: CASSANDRA-4311 clean up messagingservice protocol limitations
• supercedes: CASSANDRA-4101 Gossip should propagate MessagingService.version
