We have done the exercise "astronauts-in-space", and the biggest problem was, that the example is pretty old, and you have to use Java 1.8 for it. Combined with that, the libraries are much older, and that leads to all the time, that you have to try out which version for which exercise is working.

Goal: Upgrade the Java version at least to Java 11 or even Java 16, and ensure that all libraries are updated as well.

Possible implementation

• Create a new (dummy) project by using https://start.spring.io/ (Spring Initializer). ✔️
• Ensure that the "right" dependencies were selected. ( ✔️ )
• Use that project as starting point, and move the code from this project over to it. ✔️
• Ensure that the project is building all the time, and the one (fake) test is running. ✔️

Details

I had to merge the POM somehow, not sure if I got all right. I have added needed libraries (for MariaDB, H2, ...) that are needed later in the exercises, so that students just may use them.

Left over is the upgrade of JUnit 4 to JUnit 5 (at least), not sure, if I am able to do that in the same ticket.

Btw, I have migrated to Java 11, tests were running in Java 16, but the application had problems when starting. I think Java 11 is reasonable, the Spring Boot Initializer was used with Java 16 (if that is relevant).
