Environment variables mapped through the JkEnvVar (mod_jk 1.2) are present in the request.getAttribute(xxx) but not in request.getAttributeNames().

           Summary: Environment variables mapped through the JkEnvVar
                    (mod_jk 1.2) are present in the
                    request.getAttribute(xxx) but not in
                    request.getAttributeNames().
           Product: Tomcat 5
           Version: 5.0.19
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Connector:Coyote
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: remus@nolimits.ro


Environment variables mapped through the JkEnvVar (mod_jk 1.2) are present in 
the request.getAttribute(xxx) but not in request.getAttributeNames(). 
 
As it turns out in 
jakarta-tomcat-catalina/catalina/src/share/org/apache/coyote/tomcat5/CoyoteRequest.java 
getAttribute method is properly implemented but in the getAttributeNames the 
attributes comming from the coyoteRequest are not taken into consideration 
(the same might happen in Tomcat 4 too, didn't tested) 
 
I made a patch to correct the behavior, however not being very familiar with 
the tomcat sources the patch corrects the above described behavior but might 
not be in line with your way of doing things so feel free to adjust on it. 
 
Best regards, 
	Remus
