Whenever `camel-quarkus-xml-jaxb` is on the classpath it is not possible to
successfully produce a native application.

I think it's related to
https://github.com/quarkusio/quarkus/commit/3ff5a163633af6fc076f7ddf700a3c7c285f7b44
and specifically this code:
```
@Alias
@RecomputeFieldValue(kind = RecomputeFieldValue.Kind.FromAlias)
private Map<Class<? extends Annotation>, Map<Package, Annotation>>
packageCache = new HashMap<>();
```
Similar to
https://github.com/quarkusio/quarkus/issues/3300#issuecomment-653002628, I
think
[creation](https://github.com/apache/camel-quarkus/blob/main/extensions-core/xml-jaxb/runtime/src/main/java/org/apache/camel/quarkus/component/xml/jaxb/XmlJaxbRecorder.java#L37)
of the JAXBContext in our `xml-jaxb` extension messes up the
`RecomputeFieldValue`. It seems to work fine if it's changed to:
```
@RecomputeFieldValue(kind = RecomputeFieldValue.Kind.NewInstance, declClass
= HashMap.class)
```
