Interface shows error messages refer it as class

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.
