> I found this problem when I was working on
> [KAFKA-12324|https://issues.apache.org/jira/browse/KAFKA-12324].
> As of present, Kafka Connect and Trogdor are using Jetty 9. Although Jetty's
> stable release is 9.4, the Jetty community is now moving their focus to Jetty
> 10 and 11, which requires Java 11 as a prerequisite. To minimize potential
> security vulnerability, Kafka should migrate into Java 11 + Jetty 11 as soon
> as Jetty 9.4 reaches the end of life. As a note, [Jetty 9.2 reached End of
> Life in March
> 2018|https://www.eclipse.org/lists/jetty-announce/msg00116.html], and 9.3
> also did in [February
> 2020|https://www.eclipse.org/lists/jetty-announce/msg00140.html].
> In other words, the necessity of moving to Java 11 is heavily affected by
> Jetty's maintenance plan. Jetty 9.4 seems like still be supported for a
> certain period of time, but it is worth being aware of these relationships
> and having a migration plan.
> Updating Jetty to 11 is not resolved by simply changing the version. Along
> with its API changes, we have to cope with additional dependencies, [Java EE
> class name changes|https://webtide.com/renaming-from-javax-to-jakarta/],
> Making Jackson to compatible with the changes, etc.
> As a note: for the difference between Jetty 10 and 11, see
> [here|https://webtide.com/jetty-10-and-11-have-arrived/] - in short, "Jetty
> 11 is identical to Jetty 10 except that the javax.* packages now conform to
> the new jakarta.* namespace.".
