what seems to be a bug in getDeclaredConstructors(). Will check back later.

OuterClass.java

public class OuterClass
{
    private int x;
    private OuterClass(int x){
        this.x =x;
    }
    public static void main( String[] args )
    {
        // Should print 1 constructor not 2
        System.out.println(OuterClass.class.getDeclaredConstructors().length); // prints 2
    }

    public static class NestedClass{
        private int x =0;
        public NestedClass(int x){}

        // This is not a constructor. Yet,  App.class.getDeclaredConstructors() counts it as a constructor!
        public OuterClass foo(){
            return new OuterClass(10);
        }

    }
}
