Support for jackson-jakarta-rs-json-provider (Jackson 2.13)

[metaxmx]

Since the recently released version 2.13 of Jackson there is a new module jackson-jakarta-rs-json-provider, which is the Jakarta-replacement of jackson-jaxrs-json-provider (using the jakarta instead of the deprecated javax namespace).
However, the Jersey module jersey-media-json-jackson still uses only the jackson-jaxrs-json-provider module and is not compatible to the new Jackson module due to changed packages and class names.

Would you kindly provide a way to use the new Jackson version with Jakarta-XmlBind together with Jersey.

Note: there is already a ticket in the Jackson repository concerning this issue: FasterXML/jackson-modules-base#153

My project suffers from exactly the same thing. It would be nice to have a fix. Thanks.

Big plus one for this, I could give it a shot. Maybe I need some help from @jansupol.

There are some pitfalls when using JAX-B 3/4 (jackson-module-jakarta-xmlbind-annotations) with Jackson module regarding compatibility.

1. What we probably want is to support only one version of JAX-B, that is JAX-B 3/4.
2. At the same time, we want to support older applications that used to work well with JAX-B 2 (jackson-module-jaxb-annotations). and we want these apps to keep working when using the new Jersey.

One option is to have multiple modules, 0ne for JAX-B 2, one for JAX-B 3. That seems to have a bunch of disadvantages (code duplication, module naming, maintenance...).
A better option is to support both JAX-B 2 and JAX-B 3 at the same time by a single module. That seems to be possible by making dependency on JAX-B 2 optional. That way, the existing application contains the JAX-B 2 dependency and will keep working.

At the same time, we do not want to have the dependency on JAX-B 3 optional. We want to have the Jackson module bring over the required dependencies. The required dependency would be jackson-module-jakarta-xmlbind-annotations. This requirement breaks the existing applications. However, adding the required dependency would be enough, and we consider it the best option.

The proposal is #4963.
