How to make method from superclass available in reflection config?

[borkdude]

Hi!

Using this Java program:

import java.lang.reflect.Method;

public class Repro {

    public static void main (String [] args) {
        Class x = String.class;
        Method[] methods = x.getMethods();
        for (Method m: methods) {
            System.out.println(m);
        }
    }

}

I am able to see the methods:

public final native void java.lang.Object.wait(long) throws java.lang.InterruptedException
public final void java.lang.Object.wait(long,int) throws java.lang.InterruptedException
public final void java.lang.Object.wait() throws java.lang.InterruptedException
...
public final native void java.lang.Object.notify()
public final native void java.lang.Object.notifyAll()

in a native image compiled from this Java program, if I provide the following reflection config:

[{"name" : "java.lang.String",
  "allPublicMethods" : true}]

However, I would like to keep my program small and want to make available wait and notify for a large number of classes without any other methods.

I tried:

[{"name" : "java.lang.String",
  "methods": [{"name": "notify"}]}]

but this results in an error message:

Error: Error parsing reflection configuration in /private/tmp/reflection.json:
Method java.lang.String.notify() not found

So, how do I make available the Object.notify() method on the String class reflection config?

I may have found a solution. When I only include String without any other methods and also notify from Object, I see them both in the native image:

[{"name": "java.lang.Object",
  "methods": [{"name": "notify"}]},
 {"name": "java.lang.String"}]

public java.lang.String java.lang.String.toString()
public final native void java.lang.Object.notify()
