widen viewMessages(int From, int To) and getMessageCount() AMQQueueMBean
methods to use Long values
---------------------------------------------------------------------------------------------------
Key: QPID-1961
URL: https://issues.apache.org/jira/browse/QPID-1961
Project: Qpid
Issue Type: Sub-task
Components: Java Broker, Java Management : JMX Console
Affects Versions: M4, M3, M2.1, 0.5
Reporter: Robbie Gemmell
Assignee: Robbie Gemmell
Priority: Minor
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.
