the class Follower method isLeaderAvailabilityKnown.

private boolean isLeaderAvailabilityKnown() {
    if (leaderId == null) {
        return false;
    }
    Optional<Cluster> cluster = context.getCluster();

    if (leaderActor == null) {
        return false;
    }
    Address leaderAddress = leaderActor.anchorPath().address();
    CurrentClusterState state = cluster.get().state();
    Set<Member> unreachable = state.getUnreachable();
    log.debug("{}: Checking for leader {} in the cluster unreachable set {}", logName(), leaderAddress, unreachable);
    for (Member m : unreachable) {
