Description

A couple of recent updates appear to have broken o.a.c.d.t.GossipTest

• There seems to have been a merge/commit race between CASSANDRA-16146 (fee7a108) and CASSANDRA-15935 (41952a2f). The former adds a ByteBuddy interception on StorageService::bootstrap, but the latter changed the method signature, so this never actually gets injected. This causes a latch in the test not to be counted down and it hangs until timeout.
• After fixing the test code, it still hangs due to changes to server_encryption_options initialization in CASSANDRA-16144 (f293376a). It appears to be causing an incorrect keystore location to be specified, which causes instance startup to fail, again leading to the test hanging until it times out. I don't have the cycles to dig into this further right now, but reverting that commit (and making the test fix above) restores the green bar.
