    29   * Java Bean {@link java.beans.PropertyEditor} which converts Strings into
    30   * {@link InetSocketAddress} objects. Valid values include a hostname or ip
    31   * address and a port number separated by a ':'. If the hostname or ip address
    32   * is omitted the wildcard address will be used. E.g.:
    33   * <code>google.com:80</code>, <code>:22</code>, <code>192.168.0.1:110</code>.
    34   * <p>
    35   * Use Spring's CustomEditorConfigurer to use this property editor in a Spring
    36   * configuration file. See chapter 3.14 of the Spring Reference Documentation
    37   * for more info.
