How to add a custom jar for custom ValidConnectionChecker class in EAP6?

Issue

• We would like to use our own implementation for ValidConnectionChecker and load it in the same datasourec configuration.
• The custom ValidConnectionChecker class is not getting picked up, giving the following exception:

15:38:00,137 WARN  [org.jboss.jca.adapters.jdbc.local.LocalManagedConnectionFactory] (ConnectionValidator) Exception trying to create valid connection checker (disabling):: java.lang.Exception: Unable to load: abc.xyz.ValidConnectionChecker
    at org.jboss.jca.adapters.jdbc.BaseWrapperManagedConnectionFactory.loadPlugin(BaseWrapperManagedConnectionFactory.java:1027)

    at org.jboss.jca.adapters.jdbc.BaseWrapperManagedConnection.checkValid(BaseWrapperManagedConnection.java:518)

• We would like to use our custom implementation of ExceptionSorter or StaleConnectionChecker.
