      I noticed while converting tomcat-native to an SCL package that even though tomcat loads tcnative into memory it doesn't default to using Http11AprProtocol anymore (when protocol="HTTP/1.1" is used) . Instead it's setup to use OpenSSL/NIO instead of APR because it is more reliable and more beneficial for users.

      We should document this change so that when users upgrade they're aware that APR needs to be explicitly configured.

      To re-enable the behavior from previous versions (default to APR, if available), users can set useAprConnector="true" on the AprLifecycleListener defined in the server.xml and restart.
