           Summary: Parser chokes on tags within HTML comment block
           Product: Tomcat 5
           Version: 5.0.28
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: major
          Priority: P2
         Component: Jasper
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: terri.paik@webmethods.com


The following valid JSP loaded fine in Tomcat 4, but it does not load in Tomcat 
5. The parser is complaining about the unbalanced end tag </mycomp:foo> which 
is within an HTML comment. This is incorrect; a tag inside a comment block 
should be ignored. 

<%@ page language="java" contentType="text/html" %>
<%@ taglib uri="http://webm-taglib.tld" prefix="mycomp" %>
<html>
<P>This is a plain JSP that serves up HTML.
<!-- 'foo' tag
  Use the 'foo' tag to make coffee in the morning.  Remember to include
  a closing foo tag, e.g. </mycomp:foo>.
-->
</html>

Exception thrown is:
org.apache.jasper.JasperException: /apachebug.jsp(8,26) The end 
tag "&lt;/mycomp:foo" is unbalanced
