  - Previously published fixes for log4jshell turned out to be incomplete.
       Upstream has followed up on the original patch for CVE-2021-44228 with
       several additional changes (LOG4J2-3198, LOG4J2-3201, LOG4J2-3208, and
       LOG4J2-3211) that are included in this update. Since the totality of
       those patches is pretty much equivalent to an update to the latest
       version of log4j, we did update the package's tarball from version
       2.13.0 to 2.16.0 instead of trying to apply those patches to the old
       version. This change brings in a new dependency on 'jakarta-servlet' and
       a version update of 'disruptor'. [bsc#1193743, CVE-2021-45046]
