Exposing private type via a public getter/setter method

The class com.sun.xml.wss.provider.wsit.ConfigHelper contains
get/setConfigData() methods that expose an inner private ConfigData class.
Please fix it by either lowering the getter/setter visibility or increasing the
ConfigData class visibility, as appropriate.

Start by locating com.sun.xml.wss.provider.wsit.ConfigHelper and inspecting the visibility of ConfigData and its getConfigData()/setConfigData() methods. Confirm that the public API no longer exposes a private type, choosing the visibility arrangement appropriate for the class design; no file or test is named in the issue.
