Jaakko Laine commented on CASSANDRA-572:
----------------------------------------

Run into one tricky issue with STATE_LEAVING. I'll check that tomorrow with #603 as they are
connected.

> (1) If a node has been moving in the ring, further bootstraps by other nodes will cause
errors as they are handling STATE_LEAVING gossip without having such member in token metadata.
> (2) When a node bootstraps, it handles all ep states in the order they happen to arrive.
If the first one to arrive has moved in the past (that is, it has STATE_LEAVING in its ep
state), getNaturalEndpoint will throw ArrayIndexOutOfBounds exception as sortedTokens.size()
== 0.
