> The viewMessages() operation is inherently limited to viewing the first 2^31 undelivered messages on the queue at any given time due to its use of int parameters. Equally, getMessageCount() returns an int value. However, the SimpleAMQQueue implementation is not limited to 2^31 messages and so there is potential that not all messages can be viewed.
> This should be rectified by increasing the parameter range to Long. The viewMessages() implementation will then be limited to viewing ANY 2^31 messages on the queue as the TabularData OpenData result sets used to support generic JMX clients are also fixed in size by an int index.
