Hover support for property keys that reference values from a file loaded with java.util.Properties

Current Result

Expected Result

When I import one .properties file
I hope to be able to directly and intelligently prompt the value in the properties file when using the key keyword in the properties file when compiling the content.

object.properties
First.Value=SomeValue

.java file
import java.io.;
import java.util.;

public class testProperties {
public static void main(String[] args) throws FileNotFoundException, IOException {

    Properties prop = new Properties();
    prop.load(new FileInputStream("C:\\my_code\\object.properties"));
    String someKey = "First.Val";
    String abc = prop.getProperty(someKey);
}

}

I hope when the mouse is placed on the penultimate line of first Val can get relevant information

Additional Informations

Reproduce the Java example with object.properties and the prop.getProperty call in VS Code, noting the requested hover behavior and the First.Val versus First.Value mismatch. Trace the existing Java hover handling and determine how the loaded properties file could be connected; done means hovering the property key shows its corresponding value.
