      Description

      FULL PRODUCT VERSION :


      A DESCRIPTION OF THE PROBLEM :
      In JDK 8, we can provide the implementation of method with the help of static and default keyword. We can't run interface before JDK 8 but now we can provide main method implementation inside interface and we can run it... I have implemented main method inside interface and run the program. It was working fine.. but I comment in main method and try to run program I got error "Error: Main method not found in class org.vc.TestI, please define the main method as:
         public static void main(String[] args)
      or a JavaFX application class must extend javafx.application.Application"

      Beauce we are running interface so there should be interface instead of class in error message.
       Error message should be "Error: Main method not found in interface org.vc.TestI, please define the main method as:
         public static void main(String[] args)
      or a JavaFX application class must extend javafx.application.Application"

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Error: Main method not found in interface org.vc.TestI, please define the main method as:
         public static void main(String[] args)
      or a JavaFX application class must extend javafx.application.Application
      ACTUAL -
      Error: Main method not found in class org.vc.TestI, please define the main method as:
         public static void main(String[] args)
      or a JavaFX application class must extend javafx.application.Application

      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      package org.vc;

      public interface TestI {

        /* public static void main(String[] args) {
      System.out.println("Hi...");
      getMsg();

         }*/
         
         public static void getMsg(){
      System.out.println("method");
         }
          void getData();
      }
      ---------- END SOURCE ----------
