Checking of boxed primitives (e.g. `Double`) for `case null` with JEP 441

[gorankarlic]

Does not properly support checking of boxed Double or Float for case null with JEP 441 pattern switching. Instead it shows Case constants in a switch on 'Double' must have type 'double' Java(2099252).

Environment

• Operating System: MacOS 15.0.1
• JDK version: JDK 21
• Visual Studio Code version: Version: 1.94.2 (Universal)
• Java extension version: v1.35.1

Steps To Reproduce

public class Test
{
    public static void main(final String[] args)
    {
        switch(Double.valueOf(1.0))
        {
            case null -> System.out.println("is null");
            default -> System.out.println("is not null");
        }
    }
}

Current Result

This displays the following error in VSCode:

Case constants in a switch on 'Double' must have type 'double' Java(2099252)

Expected Result

As Java 21 compiles and runs the above code it should not show an error.
