Jersey 3.x uses the *Jakarta* namespace, which introduces some compatibility
considerations with Jetty versions:
* *Jetty 9.x* is *EOL* and must be upgraded.
* *Jetty 12 EE8* supports the legacy *{{javax}}* namespace.
* *Jetty 12 EE10* supports the newer *{{jakarta}}* namespace.
>From my initial work on the patch, here's how Jersey versions map to Jetty:
* *Jersey 3.0.x* requires {*}Jetty 11{*}, which has also reached *EOL* and is
no longer community-supported.
* *Jersey 3.1.4+* requires {*}Jetty 12 EE10{*}, aligning with the *Jakarta
namespace* and offering long-term support.

Given that both Jetty 9 and 11 are EOL, and that Jersey 3.1.4+ requires EE10,
the cleaner long-term approach would be to migrate directly to {*}Jersey 3.1.4+
with Jetty 12 EE10 (requires JDK 17){*}.
Would like to confirm if this is the right direction before proceeding further.
was (Author: JIRAUSER302593):
Jersey: 3.x supports the Jakarta namespace.
Jetty: 9.x is EOL and needs to be upgraded. Jetty 12-EE8 supports the javax
namespace, whereas jetty 12-EE10 is with the Jakarta namespace.
I have started working on this patch and see that migrating to:
# Jersey 3.0.x will require migration to Jetty 11.
# Jersey 3.1.4+ will require migration to Jetty 12:EE10.

Looks like some work on this has been done in:
