             Bug #: 51508
           Summary: Using generic URL in jsp-config breaks welcome file
                    handling
           Product: Tomcat 7
           Version: trunk
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
        AssignedTo: dev@tomcat.apache.org
        ReportedBy: knst.kolinko@gmail.com
    Classification: Unclassified


Using 7.0.19 release candidate

Steps to reproduce:

1. Go to webapps/examples/WEB-INF/web.xml,
find existing <jsp-config> element in the file,
add the following text at the end of that element:

    <jsp-property-group>
        <url-pattern>/*</url-pattern>
        <trim-directive-whitespaces>true</trim-directive-whitespaces>
    </jsp-property-group>

2. Clear work directory. Start Tomcat.

3. Navigate to http://localhost:8080/examples/jsp
Expected result: list of examples, jsp/index.html
Actual result:

Error 500 page
org.apache.jasper.JasperException: File "/jsp" not found
   
org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:55)
   
org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:409)

Additional notes:
------------------
1. The following URLs for the same page do work:
http://localhost:8080/examples/jsp/
http://localhost:8080/examples/jsp/index.html

The following URL does not work:
http://localhost:8080/examples/jsp

So it seems that it is redirection from
http://localhost:8080/examples/jsp -> http://localhost:8080/examples/jsp/
that breaks.

2. Calling a JSP page directly does work,
http://localhost:8080/examples/jsp/jsp2/tagfiles/hello.jsp
