[Scons-users] Javac scan '.java' file less some '.class' file

[Bill Deegan]

I beleive this construct is called "anonymous inner class", is that correct?

public class Example_demo{
    public static void pppp() {
        MyInterface<List<String>> obj = null;        obj = new
MyInterface<List<String>>() {
            @Override
            public String getName() {
                return "MyInterface";
            }
            public String value() {
                return "ABC";
            }
        };
    }
}

If so, please change the title of your github issue to "SCons doesn't
properly process anonymous inner class"
