The source of problem seems to be in EmbeddedServletContainer.java. First we 
create a socket, get its port number, release the socket and use this port to 
create server:
{noformat}
        ServerSocket ss = new ServerSocket(0);
        port = ss.getLocalPort();
        ss.close();
        server.getConnectors()[0].setHost(host);
        server.getConnectors()[0].setPort(port);
