HttpClient loops endlessly while trying to retrieve status line

           Summary: HttpClient loops endlessly while trying to retrieve
                    status line
           Product: Commons
           Version: Nightly Builds
          Platform: All
               URL: http://localhost:19
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: HttpClient
        AssignedTo: commons-httpclient-dev@jakarta.apache.org
        ReportedBy: ck@rrzn.uni-hannover.de


When fed with the wrong URL, for example http://localhost:19/ (chargen port),
HttpClient will loop endlessly while attempting to read the status line.

This is caused by a bug in HttpMethodBase.readStatusLine(HttpState, HttpConnection)

(while loop without any exceptional abort condition).
