Invalid Java code generation from JSP 

           Summary: Invalid Java code generation from JSP
           Product: Tomcat 5
           Version: 5.0.19
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: Jasper
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: d_bajracharya@yahoo.com


An object named clientList of type ArrayList is passed to JSP page from servlet.
In JSP page, as part of jsp:useBean, java.util.List is specifed and scope
specified is request. 
(<jsp:useBean id="requestData" scope="request" class="scrub.util.RequestData" />)
The generated JAVA page fails to compile due to an attempt to create
java.util.List if the passed object is null. I think the generated code should
not try to create. The support for interface is very important.

Code snippet:

         java.util.List clientList =
_jspx_page_context.getAttribute("clientList");
        if (clientList == null){
           clientList = new java.util.List();
           _jspx_page_context.setAttribute("clientList", clientList,
PageContext.REQUEST_SCOPE);
         }
