i'm stuck a bit here on the jaxrs-json module, the provides clause, you can only have either javax. or jakarta.
but moditect right now can't run twice or target the shade that i can figure out.....

for now i've got a shade of 12.2rc2 running with my changes of the affected modules, i'm just going to deploy then i'll put the coordinates here for testing

this is tested in the https://github.com/FasterXML/jackson-jdk11-compat-test project
