Base class methods are missing when generating override methods with source action.

[Kidsunbo]

[provide a description of the issue] When instantiating an anonymous class, I would like to use source action to override some methods in the base class. But the methods in base class don't show up in the quick pick list.

Environment

• Operating System: Ubuntu (24.04)
• JDK version: 21
• Visual Studio Code version: 1.89.1
• Java extension version: 1.30.0

But this issue seems not related to the OS.

Steps To Reproduce

1. [step 1] Creating a Java project with the following code:

   
   public class App {
   public static void main(String[] args) throws Exception {
       System.out.println("Hello, World!");
       Base s = new Base(){
   
       };
   }
   }

class Base{ public void hello(){

}

public void hey(){

}

}

2. [step 2]

At the position of `new Base()`, right click and select `Source Action` and select `Override/Implement Methods`. There is no `hello` and `hey` in the options.

##### Current Result
No `hey` and `hello`

##### Expected Result
The two methods exist.

##### Additional Informations
I have already tried Eclipse and it work well for such operation.

As a workaround, if you start typing he in the body of new Base(){ };, you should get completion to override those methods

Thanks and I've taken this workaround. Not a big deal, but I think it's worth repairing. BTW, i find that it seems to be an upstream issue as the extension only wrap the result returned by the language server.

Sorry for the misleading, I found that it seems not to be a bug. If I right-click at the base class name, the language server searches the overridable methods of the outer class. When right-clicking between the braces of the base class, it works well.
