Description

Jakarta EE 9 is out already along with stable versions of the two most popular containers - Tomcat 10 and Jetty 11 (running on Servlet 5.0). `log4j-web` internally still uses `javax` (e.g. here) so it is incompatible with an application that runs on these two containers. It would be nice to release a new version that is compatible with them. Unfortunately a single version cannot be made compatible with both the "old" `javax` and the "new" `jakarta` namespaces so perhaps a new major one should be released.
