Usage of ibatis just doesn't want to fully go away. I'm well aware of many usages up through jdk 17 using spring 5 latest. This logic was originally pulling the source but then switched to doing so without copying springs code in case they made updates. Well, its been many years, there won't be updates, so pom needs reworked to slurp in source more closely to how it works now with ability to do that one of if ever needed (unlikely) and then code needs managed up to spring 5 (internals). That will further allow feasibility of going to spring 6 in a subsequent release.
