     [ http://jira.jboss.com/jira/browse/JBESB-683?page=all ]

Mark Little resolved JBESB-683.
-------------------------------

    Resolution: Done

Have added a getValue operation that behaves like getProperty in System. Updated comments to reflect differences in null behaviour.

Will close and checkin once MR3 is out.

> The normal assumption of null for a default value (e.g., in System.getProperty) is that you return null if there is nothing set. However, in ListenerUtil, if you pass null as a default value this means throw a ConfigurationException on finding null for the value. This is not intuitive and goes against all other similar mechanisms. If we need this capability, then let's add an explicit method for throwing an exception, or another parameter.
