> Project: Qpid
> Issue Type: Bug

> Affects Versions: 0.28
> Reporter: Pavel Moravec
> Assignee: Pavel Moravec
> Priority: Trivial
> Fix For: 0.29

> opened == True. After unsuccessfull connection, the state of Connection
> object should be False.
> How reproducible:
> 100%
> Steps to Reproduce:
> 1. create a connection to nonexisting broker in python
> 2. check return value od connection.opened()
> (or see below reproducer)
> Actual results:
> True
> Expected results:
> False
> Reproducer script:
> from qpid.messaging import *
> parms = {}
> try:
> connection = Connection("invalid-hostname", **parms)
> connection.open()
> except ConnectionError,e:
> print e
> print "connection.opened=%s" %(connection.opened())
