        RFC 7230 states that clients should ignore reason phrases in HTTP/1.1
        response messages. Since the reason phrase is optional, Tomcat no longer
        sends it. As a result the system property
        <code>org.apache.coyote.USE_CUSTOM_STATUS_MSG_IN_HEADER</code> is no
        longer used and has been removed. (markt)
