> 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.

> 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:
> 15:41:21,960 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception
