Error when doing listStatistics operation on datasource with twiddle: ClassNotFoundException: JBossManagedConnectionPoolStatistics

Issue

When trying to use twiddle to do "listStatistics" operation on a datasource (example: DefaultDS):

twiddle.sh -s ip-address:1099 -u admin -p pass invoke jboss.jca:service=ManagedConnectionPool,name=DefaultDS listStatistics

The following error happens:
