in locking when tx is not used. We are fixing that in release 1.2.
Do I need locking when I am "getting" a value that is already in a node's map?  
I do not care if other items are added to the map while I am "getting" this 
value do I?  Is the issue you refer to the reason I am getting null?

the aop part.
So far, when I am using the TreeCacheAop methods, I have not had any issues.  
This problem only occurs when using TreeCache's put/get methods.  That said, 
would this refactoring be of any help?

out to troubleshoot is to write a JUnit test case. That can cut down the time 
that I need to generate one by myself. Besides, I can check in your test case 
in the src tree as well.
I can try to create one, but this only seems to happen under high load (and 
with multiple nodes), and then, it does not happen everytime.
