> On line 164 of {{org/apache/cassandra/transport/Server.java}}, the cause of a failure
to bind to the server port is swallowed:
> [https://github.com/apache/cassandra/blob/06209037ea56b5a2a49615a99f1542d6ea1b2947/src/java/org/apache/cassandra/transport/Server.java#L163-L164]
> {code:java}
>         if (!bindFuture.awaitUninterruptibly().isSuccess())
>             throw new IllegalStateException(String.format("Failed to bind port %d on
%s.", socket.getPort(), socket.getAddress().getHostAddress()));
> {code}
> So we're told that the bind failed, but we're left guessing as to why. The cause of the
bind failure should be passed to the {{IllegalStateException}}, so that we can then proceed
with debugging, like so:
> {code:java}
>         if (!bindFuture.awaitUninterruptibly().isSuccess())
>             throw new IllegalStateException(String.format("Failed to bind port %d on
%s.", socket.getPort(), socket.getAddress().getHostAddress()),
>                 bindFuture.cause());
> {code}
