    • We collect Confluence feedback from various sources, and we evaluate what we've collected when planning our product roadmap. To understand how this piece of feedback will be reviewed, see our Implementation of New Features Policy.

      NOTE: This suggestion is for Confluence Server. Using Confluence Cloud? See the corresponding suggestion.

      Would like to see Tomcat 8.5.6 or 9.0 added behind our applications as this will enable us to utilise HTTP/2 with NIO protocols and drastically improve performance for throughput and speed to our clients. By using HTTP/2 at the proxy level, we have seen as much as a 65% improvement in application speed. If we can add HTTP/2 (h2) at the Tomcat layer, we can increase that by as much as 85% - which would be a huge win for our applications.

      Additionally, Tomcat 8.0.x goes EOL on 30 June 2018: https://tomcat.apache.org/tomcat-80-eol.html

            [CONFSERVER-44949] Add Support for Tomcat 8.5 or later

            To be fair to our Developers, Confluence does not use Tomcat 7. It is presently on Tomcat 8.0.50, and 8.5 was not a full release when the FR was written. The feature request is gathering interest as that is the present status when this was written originally (my request in late 2016).  Personally would love to have Tomcat 9.x be the back end application server, but testing does take time. If you have a version of Confluence running on Tomcat 7, it is likely already an end-of-life version of Confluence. I would encourage you to review the End of Support Announcements for Confluence as the developers are actively testing many items at once to correct the product.

            Please acknowledge reality that some companies and data centers won't allow operation of unsupported server software, which Tomcat 8.0 is after EOL by 30 June 2018.

            I agree with Michael, besides Tomcat 8.0.x is going to End of Life soon (see here). Which is the roadmap of Atlassian to facing that problem ? Thanks in advance

            I don't undersand that Atlassian does not update core components to new major releases. Tomcat is the foundation of Confluence server. Version 7, which Confluence currently uses is from 2011 (but still supported). Tomcat 8.5, which is stable since 2 years now, has many features (like HTTP/2) which are worth for updating. Now, since 1 month even Tomcat 9 is declared stable by Apache.

            So why is this feature request still in "Gathering interest"? It should be in the interest of Atlassian to keep their core components up to date and it should not depend on enough customers begging for such an update.
