GetMethod.java checks the "used" flag which cannot be set at this time

           Summary: GetMethod.java checks the "used" flag which cannot be
                    set at this time
           Product: Commons
           Version: Nightly Builds
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: HttpClient
        AssignedTo: commons-httpclient-dev@jakarta.apache.org
        ReportedBy: max@linuxtag.org


GetMethod.getResponseBodyAsStream calls HttpMethodBase.checkUsed, which asserts
the flag "used" is "true". But at this time, "used" cannot be true, as "used" is
set to true in HttpMethodBase.processRequest, two lines after readResponse is
called (which in turn calls readResponseBody / readResponseBodyAsStream).

Maybe "requestSent" is the flag which should be checked instead of "used"?

My stack trace: (fragment)

java.lang.IllegalStateException: Not Used.
