javac throws NullPointerException when the Wrong Program was compiled.

[苦狐]

Hi.

The Java Compiler which is
version-1.8.0-ea(lambda-8-b1314-windows-x64-10_nov_2011) throws
NullPointerException when the program  which should be Compile Error was
compiled.

This is the code of that wrong program.

// vvvvvvvvvvvvv Code vvvvvvvvvvvvv

public class Main
{
    public /*static*/ class Class1 // NOT static
    {}

    public interface Constructor0<RET>
    {
        public RET createInstance();
    }

    public static void main(String[] args)
    {
        // Illegal Constructor Reference
        Constructor0<Class1> c = Main.Class1#new; // should be Compile
Error, NOT Compiler's Exception
    }
}

// ^^^^^^^^^^^^^ Code ^^^^^^^^^^^^^

We can understand this program is wrong, but The Java Compiler should tell
us that by the Compile Error, NOT Compiler's Exception.
Please check this problem.

This is the Message from javac, and the StackTrace.
