The code in VersionProps.versionNumbers() could be slightly refactored in order to  provide an entry point for unit testing:

...
class VersionProps {
  . . .
  static List<Integer> parseVersionNumbers(String versionNumber) {
      // parsing code goes there
  }
  static List<Integer> versionNumbers() {
      return parseVersionNumbers(VERSION_NUMBER);
  }
  . . .
}
...

This would allow writing/adding a unit test for the algorithm implemented in parseVersionNumbers (either using white-box with -Xpatch or using reflection and the proper incantations to invoke parseVersionNumbers from outside the package).
