Running the current 0.7.0-beta2 #3 build, I get the error below when checking tpstats via node_tool.
The MessagingService is registering itself as a mbean in org.apache.cassandra.concurrent, and the MessagingServiceMBean interface does not support the getActiveCount(), getCompletedTasks() and getPendingTasks() functions of the IExecutorMBean.
Out of interest should it be registering the JMXEnabledThreadPoolExecutor it created on line 105, or should it be registered elsewhere?
It's still possible to view the task pool info through jconsole.
I'll create a bug when Jira finishes re-indexing :)
