Cleanup tests using Java records

[LorenzoBettini]

When Java 17 PR is merged, tests using Java records, based on assuming Java 21, should be updated NOT to check for Java 21 since records have been present since Java 17. Also remove dep on draw2d just for referring to a Java record: we can have a Java record as part of our testdata.
