Do we need to break compatibility with older Java software to support Jackson 3?

If we cannot release without this Java version update, we should increase the major version number in this release to clearly mark that it is breaking backward compatibility.

Jackson 3 build with JDK17, older JDK will not be able to read classes, so yep, we need this.
