When using the latest version of the OGC API plugin, the core /rest API breaks
with JSON payloads. For example, than it is no longer possible to create a
workspace by using a JSON payload.
Steps to reproduce:
1. Download latest GeoServer WAR and latest OGC API plugin.
2. Deploy it within Tomcat.
3. Try to create a workspace as follows:
curl -v -u admin:geoserver -X POST \
-H "Content-type: application/json" \
-d '{"workspace":{"name":"test"}}' \
http://localhost:8080/geoserver/rest/workspaces
Within the GeoServer logs you will find the following stack trace:
17 Jan 14:35:19 ERROR [geoserver.rest] - Type definition error: [simple type,

On further investigations I have noticed that the OGC API plugin registers a
custom MappingJackson2HttpMessageConverter :
https://github.com/geoserver/geoserver/blob/main/src/community/ogcapi/ogcapi-core/src/main/java/org/geoserver/ogcapi/APIDispatcher.java#L156
(
https://github.com/geoserver/geoserver/blob/main/src/community/ogcapi/ogcapi-core/src/main/java/org/geoserver/ogcapi/APIDispatcher.java#L156
)
By commenting out this line, the core /rest API does not break and the above
request works as expected.
Just an idea: It seems like that some Jackson mappers are lost from core, when
the OGC API plugin registers the custom converter.
