Alex Rudyy updated QPID-3530:
-----------------------------
Description:
The current functionality of QueueBrowser on 0-8/0-9/0-10 code paths behaves
differently when failover happens. QueueBrowsers on 0-10 path invoke
receiveNoWait() in order to browse the queue while QueueBrowsers on 0-9 path
invoke receive() method. When failover happens 0-8/0-9/0-9-1 QueueBrowsers
block and restart the browsing of the queue from the beginning after failover
is finished while 0-10 QueueBrowsers return null when invoked during failover.
QueueBrowser functionality should be changed to throw NoSuchElementException on
iteration through the queue messages when falover happens.
