On portal startup the following debug messages are shown:

12:59:07,215 DEBUG [localhost-startStop-1][JSONWebServiceActionsManagerImpl:275] A JSON web service action is already registered at /permission/check-permission
12:59:07,539 DEBUG [localhost-startStop-1][JSONWebServiceActionsManagerImpl:275] A JSON web service action is already registered at /expandovalue/add-value
12:59:07,573 DEBUG [localhost-startStop-1][JSONWebServiceActionsManagerImpl:275] A JSON web service action is already registered at /journalfeed/delete-feed
12:59:07,575 DEBUG [localhost-startStop-1][JSONWebServiceActionsManagerImpl:275] A JSON web service action is already registered at /journalfeed/get-feed
12:59:07,637 DEBUG [localhost-startStop-1][JSONWebServiceActionsManagerImpl:275] A JSON web service action is already registered at /mdrrule/add-rule

This happens because of overloading - we have methods with the same name and same parameter names, and only one such method can be registered. It is not guaranteed which one.

This LPS cleans up this confusion by exposing only one of the overloaded methods and excluding the others.

Also, this should be a WARN message, not a DEBUG one.
