If I recall correctly, there were a number of bugs related to statistics and JMX status that were fixed in the 5.6-5.9 range, so it's possible that this issue has already been fixed in a later version. (Did you search JIRA before posting this question?)
Because of that possibility, it's unlikely that anyone will put much effort into investigating unless you can show it happens in a recent version.

I've watched the MemoryPercentUsage for thirty minutes and I still haven't seen a change eventhough the memory usage in the log file changes. Why is the MemoryPercentUsage stuck on zero? -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
