Same scenario as Bug 527670 (originally I wanted to report this bug, bug stumbled Bug 527670 when using a Java 9 JRE for my minimal test case :-).

Consider the following class First:

  package org.example;

  import java.util.Arrays;

  public class First {

    public static void main(String[] args) {
Arrays.asList(args).stream().map(First::transform).forEach(System.err::println);;
    }

    public static String transform(String s) {
      return s.toLowerCase();
    }
  }

Select the declaration of "transform" and do a Refactor > Move to another type "org.example.Second".

Under Photon.M3 this breaks the code, i.e., it introduces a compilation error:

public class First {

  public static void main(String[] args) {
    Arrays.asList(args).stream().map(First::Second.transform).forEach(System.err::println);;
  }
}

The First::Second.transform part is broken.
