Oracle UCP Incorrect JMX Support

I tried out the jmx support for the universal connection pool and it seems to give incorrect values. There are couple of problems I have faced till n开发者_如何学编程ow

1. The getConnectionPoolNames() method (operation) of the UniversalConnectionPoolManagerMBean returns void instead of returning a Collection.
2. The getStatistics() method (operation) of the UniversalConnectionPoolMBean throws an NotSerializableException.

Though there are workarounds to the above problems like calling other methods instead of the above ones the issues seem to be very basic. Has anyone tried out the JMX support provided by the Universal Connection Pool (ucp)?
