1. Hi Ashish,

   I am using Jdev 12.2.1.4 version and using the Java 8 Lambda Expression, It gives the error on ruining the app. The Fast Swap is true in weblogic.xml file.

   java.lang.ClassFormatError: Class file version does not support constant tag 18 in class file

   import java.io.IOException;
   import java.io.PrintWriter;

   import javax.servlet.*;
   import javax.servlet.annotation.WebServlet;
   import javax.servlet.http.*;

   @WebServlet(name = “Consumer”, urlPatterns = { “/consumer” })
   public class Consumer extends HttpServlet {
   private static final String CONTENT_TYPE = “text/html; charset=windows-1252”;

   public void init(ServletConfig config) throws ServletException {
   super.init(config);
   }

   public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
   response.setContentType(CONTENT_TYPE);
   PrintWriter out = response.getWriter();
   out.println(“”);
   out.println(“Consumer”);
   out.println(“”);
   out.println(“The servlet has received a GET. This is the reply.”);
   out.println(“”);
   out.close();

   Runnable r = () ->{
   System.out.println(“Hello”);
   };

   r.run();
   }
   }

   Any Idea please!
