      Description

      When I uses scriplets in a jsp it sometime fails on runtime. The following example is working:

      <%@ page import="test.Class1" %>
      <%
      Class1 class1 = new Class1();
      pageContext.setAttribute("class1", class1);
      %>
      Output: ${class1}

      If I change the import so it uses "*" in the import the code fails on runtime:

      <%@ page import="test.*" %>
      <%
      Class1 class1 = new Class1();
      pageContext.setAttribute("class1", class1);
      %>
      Output: ${class1}

      If I change my EL so it uses the name of another class (class2) it is also failing:

      <%@ page import="test.*" %>
      <%
      Class1 class1 = new Class1();
      pageContext.setAttribute("class1", class1);
      %>
      Output: ${class1}

      If I use a name which dos not have the same name as a class in test package it works:

      <%@ page import="test.*" %>
      <%
      Class1 class1 = new Class1();
      pageContext.setAttribute("class1", class1);
      %>
      Output: ${dummy}

      If I exclude the scriplet part it also fails:

      <%@ page import="test.*" %>
      Output: ${class1}

      When the code fails I get the following stack trace:

      The error occurs on WildFly 10/11 but NOT on WildFly 8. I have attached the sources to an webapp showing the problem.
