Move unused and unimportant fields to local variables. pickUnusedPort() is inherently racy, so avoid using it when unnecessary. The channel's default executor is fine to use, but if you don't like it directExecutor() would be an option too. But blocking stub doesn't even use the executor for unary RPCs. Thread.join() does not propagate exceptions from the Thread; it just waits for the thread to exit.
