Loading, linking, and initializing are separate parts specified in JVM spec section 5 .
A good reference is that 3-arg Class::forName takes an initialize parameter that specifies if the class initializer should be invoked after a class is loaded.

To be clear, -—dry-run initiaizes the VM, loads the main class but the main method is not invoked. The main class’s <clinit> is not invoked.
