failed: CassandraClusteredPersistentEntitySpec
Cassandra bind problem: Failed to bind port 40361 on 127.0.0.1
https://api.travis-ci.com/v3/job/292949867/log.txt
Same kind of bind problem: https://travis-ci.com/lagom/lagom/jobs/292311699
The ports are selected in the build file using the same method as Akka's testkit util, see https://github.com/lagom/lagom/blob/81c3002c8980321499d25dc56c5a6e402cfd759b/build.sbt#L196-L208
The ports are then used on all AbstractClusteredPersistentEntityConfig. Maybe we should simply have some fixed port per test extension.
Hmm, I think this is not a problem of reserving the ports, but when connecting the client to the embedded server.
It’s a bind issue, so I think it’s starting the embedded server that fails.
https://github.com/lagom/lagom/pull/2804/files had a fix for this kind of situation, but didn't cover the CassandraClusteredPersistentEntitySpec. This seems to start in a different way.
It's about when we reserve the Cassandra port and when we start the ActorSystem.
In this failing test, we are reserving the Cassandra port in a sbt task (I don't know why), then we start the ActorSystem (it picks same port for remote) and we then start Cassandra with the port that is now in use by remote.
