>                 Key: QPID-101
>                 URL: http://issues.apache.org/jira/browse/QPID-101
>             Project: Qpid
>          Issue Type: Bug
>          Components: Java Client
>            Reporter: Marnie McCormack
>         Assigned To: Tejeswar Das
>             Fix For: M2
> Currently attempts to create a QueueBroswer result in a UnsupportedOperationException
being thrown. This needs to be corrected. (See AMQSession.createBrowser methods). 
> Note that TopicSession and QueueSession implementations correctly thrown IllegalStateExceptiuon
from these methods and do not need to be changed.
> More info from JMS 1.1 Specification follows (see spec for more details):
> 5.9 QueueBrowser
> A client uses a QueueBrowser to look at messages on a queue without removing
> them. A QueueBrowser can be created from a Session or a QueueSession.
> The browse methods return a java.util.Enumeration that is used to scan the
> queue's messages. It may be an enumeration of the entire content of a queue,
> or it may contain only the messages matching a message selector.
> Messages may be arriving and expiring while the scan is done. JMS does not
> require the content of an enumeration to be a static snapshot of queue content.
> Whether these changes are visible or not depends on the JMS provider.
