The Servlet 4.0 preview API was deprecated by Jan 2018 and removed over the last few releases as it added complexity that hindered back-ports. >From the changelog: 8.5.55: Remove the remainder of the deprecated Servlet 4 Preview API. Users still depending on this feature should ideally upgrade to Tomcat 9.0.x. If upgrade is not possible, application code should cast to the internal Tomcat implementation classes. (markt) 8.5.52: Remove PushBuilder from the deprecated Servlet 4 Preview API. Users still depending on this feature should ideally upgrade to Tomcat 9.0.x. If upgrade is not possible, application code should cast to the internal Tomcat implementation classes. (markt) 8.5.51: Remove part of the deprecated Servlet 4 Preview API. Users still depending on this feature should ideally upgrade to Tomcat 9.0.x. If upgrade is not possible, application code should cast to the internal Tomcat implementation classes. (markt) 8.5.25: ...as the early preview is now deprecated in favour of Tomcat 9 which provides a full Servlet 4.0 implementation.
