org.apache.cocoon.environment.http.HttpRequest.decode nullpointer excetion

           Summary: org.apache.cocoon.environment.http.HttpRequest.decode
                    nullpointer excetion
           Product: Cocoon 2
           Version: 2.0.2
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: core
        AssignedTo: cocoon-dev@xml.apache.org
        ReportedBy: mauch@imkenberg.de


I set encodeing of the request to utf-8 using:
ObjectModelHelper.getRequest(map).setCharacterEncoding("utf-8");

if i try to retrive a empty parameter i go a nullpointer exception:
java.lang.NullPointerException
<kabir>  at org.apache.cocoon.environment.http.HttpRequest.decode
(HttpRequest.java:300)
<kabir>  at org.apache.cocoon.environment.http.HttpRequest.getParameter
(HttpRequest.java:293

I found a problem in:
org.apache.cocoon.environment.http.HttpRequest.decode 

the str parameter is not checked for the null value, so the line

byte[] bytes = str.getBytes(this.container_encoding);

produces the exception.

A possible solution is to add as first line:
 if(str== null) return null;
and everything works fine
