Queue Size wrong

[chris . odom]

When looking at the Queue size attribute in JConsole for a particular 
Queue we noticed that the size would not reseed below a certain number 
138. The reporting of this number persisted for several hours. When I 
investigated it I looked at the Queue's operation browseMessages it 
returned what I had expected 0 messages in the Queue. Once I hit the 
resetStatistics the Queue size attribute reflects the correct number of 
messages in the Queue 0, but over time this number increases to an 
inaccurate Queue size.
