The above tests have a similar code pattern, as shown as below:
CipherTest cipherTest = new CipherTest(peerFactory);
Thread serverThread = new Thread(peerFactory.newServer(cipherTest),
          "Server");
serverThread.setDaemon(true);
serverThread.start();
System.out.println("Done");
cipherTest.run();

cipherTest may run before the server is ready.
