Inside every file in the work directory, there is an empty static block.
Code:
public class index$jsp extends HttpJspBase {


    static {
    }
    public index$jsp( ) {
    }

    private static boolean _jspx_inited = false;

    public final void _jspx_init() throws org.apache.jasper.runtime.JspException {
    }
What is the static block for? Also, what's the zero-argument constructor there for?
