/**
* Simple utility methods for working with network sockets — for example,
* for finding available ports on {@code localhost}.
*
* <p>Within this class, a TCP port refers to a port for a {@link ServerSocket};
* whereas, a UDP port refers to a port for a {@link DatagramSocket}.
*
* <p>{@code SocketUtils} was introduced in Spring Framework 4.0, primarily to
* assist in writing integration tests which start an external server on an
* available random port. However, these utilities make no guarantee about the
* subsequent availability of a given port and are therefore unreliable. Instead
* of using {@code SocketUtils} to find an available local port for a server, it
* is recommended that you rely on a server's ability to start on a random port
* that it selects or is assigned by the operating system. To interact with that
* server, you should query the server for the port it is currently using.
