Robbie Gemmell updated QPID-4419:
---------------------------------
Description:
A user recently asked for assistance (see mail thread:
http://mail-archives.apache.org/mod_mbox/qpid-users/201210.mbox/%3C1351193413.33603.YahooMailNeo%40web161402.mail.bf1.yahoo.com%3E)
in getting C++ clients working properly with the Java broker, and Java clients
working properly with the C++ broker. In the discussion it seemed to become
clear that the issue related to the (lack of) installed cyrus-sasl pacakges
affecting the supported sasl mechanisms for the C++ client and broker.
In the case of C++ client -> Java broker this resulted in attempt to initiate a
connection without specifying any Sasl mechanism. Instead of handling this by
killing the connection with a clear reason, the broker was instead incorrectly
sending a ConnectionTune reply and then subsequently killing the connection
(apparently silently and without clear reason) as a side effect of a
NullPointerException resulting from the previous lack of Sasl mechanism.
The broker handling of the missing Sasl mechanism should be improved such that
the it doesnt incorrectly send the ConnectionTune and instead kills the
connection immediately for the explicit reason that no mechnanism was specified.
The C++ client behaviour that leads to this situation will be addessed via
QPID-4407
