I have started looking at JBAS-1808 and would like to get some pointers regarding the implementation details 
* making the ManagedConnection an MBean
1) When ManagedConnection is created it should be registered as MBean.
2) The ManagedConnection MBean will have to expose the management/statistics  data.
3) Finally we need management/statistics related operations defined in MCF MBean which will look/consolidate the data. The MCF MBean being referred here is org.jboss.resource.connectionmanager.RARDeployment .

The other option
* forcing the MCF MBean to consolidate connection stats 
The org.jboss.resource.connectionmanager.RARDeployment can be updated to pull all the PreparedStatementCache data from the associated MCF instance which is available through getMcfInstance() method .
The connection creation/destruction in MCF should update the PreparedStatementCache related data in the MCF implementation(LocalManagedConnectionFactory Or XAManagedConnectionFactory) , this needs to be implemented .
This option looks complex .

Looking at the original requirement I could think of pulling the PreparedStatementCache from the JbossManagedConnectionPool MBean per DataSource.
As per the original requirement we need to 
1) Get all the ManagedConnection from the Pool.
2) Find out the PreparedStatementCache associated with these ManagedConneciton in the pool.

Here I see the related data being pulled from the JbossManagedConnectionPool/InternalManagedConnectionPool .
