Andrew Stitcher commented on QPID-3108:
---------------------------------------
When working on this fix I wanted to create a failing unit test to avoid any
regression. [Note this bug is similar to a 4 year old Jira QPID-231].
I was puzzled that I could find virtually no unit tests at all for the JMS
client code.
So I started to add one.
At first it seemed simple enough I'd create a connection object from a URL then
create a QueueSession then a QueueSender.
When I did this I realised that the Connection needs to actually talk to the
broker when you create it (to figure out which delegate to create 0_10 or 0_8
etc.) and so Ihad to have a broker running.
No problem I thought - the Java broker supports in memory brokers, it even has
a coll URL syntax, how hard can it be?
Two hours later I realised why there are no unit tests for even the simple
stuff in JMS - creating an in memory broker requires a whole chain of obscure
stuff to be there. I even found a couple of references on the mailing list and
in stackoverflow to indicate I wasn't the first to try this. There was no
indication that anyone else had succeeded though.

> Components: Java Client, JMS Compliance

> Reporter: Andrew Stitcher
> Assignee: Andrew Stitcher
> Fix For: 0.9

>
> JMS documents that you can create a QueueSender with a null queue (called an
> unidentified queue in the documentation) and this is fine as long as you
> don't try to use one fo the send methods that relies on the queue being set
> up at construction time.
> The current code checks for null queue in the getters too and so causes
> erroneous UnsupportedOperationException exceptions to be throw when they are
> used with an unidentified queue.
