Hi,

We have one module in which we store some data in Distributed state for each request and which is removed by some other process. Under heavy load when I click on listcontent() (jmx-console for DistributedState MBean) button to see the distibuted state content it gives me the below error:

RuntimeMBeanException: RuntimeException in MBean operation 'listContent()'
Cause: java.util.ConcurrentModificationException
