Review Comment:
   Have a look at 
https://github.com/search?q=repo%3Aapache%2Fhadoop%20javax.xml.bind&type=code
   
   javax.xml.bind is still used in Hadoop.
   
   I did not add this exclusion on a whim. I added it because the Haddop build 
failed with a dreaded dependency convergence exception.
   
   The tests pass with this change.





> upgrade to jackson 2.14.3

> changes. I can follow up later and try to use a newer version of Jackson but 
> this is a start.
