There is another interesting library for null-safety in Java called JSpecify: jspecify.dev/docs/user-guide

What do you think will be the output of this, assuming you run it with Java 19 (preview enabled)?
See poll below.

The correct answer is C.
The expression 'p2 instanceof Point(int x, int y) point' not only matches p2 with Point to create a variable point, but also deconstructs it into variables x and y. To do that it uses accessor methods x() and y() and therefore they get executed.

This does not happen while evaluating expression 'p1 instanceof Point point' and therefore x() and y() methods don't get executed.

Spring Data JDBC is not a complete ORM implementation and JOOQ is not ORM. But these are included as they are popular choices for interacting with databases.
