Jaxb > Jakarta, Java 8 > Java 11+, Tomcat 9 > Tomcat 10, Jersey 2 > Jersey 3, fix java errors when using java 11+ due to the improper configuration of modules in jersey<2.7. This is a huge change to dependencies and the import. Replace javax imports by jakarta imports and fix moxy xml dependencies. Please pay attention to the imports since old javax dependencies will explicitly cause Class Not found or worse : silently fail
