Description of problem:

If an exception caused by failed authentication on a broker occurs the std error is in some cases empty; see the Windows Command line transcriptions bellow:

Correct output:

Version-Release number of selected component (if applicable):
qpid-cpp-x86-2.0.0.7
Rhel5-1.3.3 and Rhel6-2.0
 

How reproducible:
10 - 30 %


Steps to Reproduce:
1. Set authentication request in the broker configuration file.
2. Restart the qpidd service on the broker.
3. Run the "spout" command in loop: C:\qpid\bin\csharp.example.spout.exe --broker dh
cp-lab-187.englab.brq.redhat.com:5672 --content "HI" --connection-options {usern
ame:guestY,password:guestY,sasl-mechanism:PLAIN} --count 1 "yy;{create:sender,de
lete:receiver}"
  

Actual results:
The std error is sometimes empty.


Expected results:
The std error should contain a message about the occurred exception.
