Replication of Scala 3 lazy val issue with Java Serialization

Run in this order:

1. sbt "run leader", wait for Waiting for cluster to form up... log message
2. sbt "run worker", it will choke on one of the first messages
3. kill leader !important!
4. run jps | grep ClusterApp | cut -d ' ' -f 1 | xargs -I {} jstack {} | grep bomb -B 9 -A 23 to see thread hanging on CountDownLatch#await()
5. add @transient to lazy val bomb: String =
6. repeat steps from 1 to 2 and check that worker node is now able to process all messages
