mixing method ref syntax and assignment

[Remi Forax]

Hi Vicente,
obviously the code below shoud be rejected because it mixes the method ref syntax with a kind of assignment, but currently javac doesn't like it at all !

public class Main {
  /*private static void all() {
    
  }*/
  
  public static void main(String[] args) = Main.all();
}

An exception has occurred in the compiler (12-amber). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program and the following diagnostic in your report. Thank you.
