I tried creating a running example from your code. I couldn't produce your exact error, but I did get something to run. It required these fixes:
- Change JavaFX version to 19 (the 11 version you have displays corrupted text on MacOS).
- Change package and module name to
com.example.dbaccess, otherwise my IDE warns me that the module name should not end in a number. - Add
requires java.sql;, otherwise, the SQL module is not visible and a session cannot be created. - Use h2 rather than MySQL. MySQL will probably work, but I didn't want to install it.
- Open your module to
org.hibernate.orm.core, otherwise hibernate can't use reflection on the entity class (which it needs to do). - Add missing code for the application, controller and fxml.
Sample code
To use, copy the code, build and run it, pressing the button to establish a hibernate session. I used OpenJDK 19.0.2 to compile and run the code via Idea.
