[jboss-jira] [JBoss JIRA] (WFLY-9368) EL expression for wildcard imports in JSP fails with "NoClassDefFoundError: Failed to link"

EL expression for wildcard imports in JSP fails with "NoClassDefFoundError: Failed to link" ------------------------------------------------------------------------------------------- Key: WFLY-9368 URL: https://issues.jboss.org/browse/WFLY-9368 Project: WildFly Issue Type: Bug Components: Web (Undertow) Affects Versions: 10.1.0.Final, 11.0.0.CR1 Environment: Windows 7, 2012R2 Reporter: Søren Friis Assignee: Stuart Douglas Attachments: WF10bug.zip 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: {{javax.servlet.ServletException:
