JasperException for JSP page using generics
-------------------------------------------
Key: JBWEB-87
URL: https://jira.jboss.org/jira/browse/JBWEB-87
Project: JBoss Web
Issue Type: Bug
Security Level: Public(Everyone can see)
Environment: Customer submitted using AS 4.2.0.GA and Sun JDK 1.5.0_11. I
verified using AS 4.2.0.GA and AS 4.2.1.GA and Sun JDK 1.6.0_02.
Reporter: David Ward
Assignee: Remy Maucherat
Fix For: JBossWeb-2.1.1.GA
I am submitting this as a JBoss Web bug; not sure if it should have been submitted as an
AS bug instead...
This test.jsp page does not compile in AS 4.2.0 or AS 4.2.1:
<%@page contentType="text/html" import="java.util.*" %>
<html><head><title>test</title></head><body>
<%
Vector<String> v =
(Vector<String>)request.getSession().getAttribute("v");
out.println("v: " + v);
%>
</body></html>
However, it does with a workaround (please see "Workaround Description"
below).
I believe that this is a bug since we require a 1.5 JVM for AS 4.2.x.
Here is the error without using the workaround:
