/**
* This method returns the properties that are located within the given property file. If the

* updated with the current values in the properties file and then the property values will be
* returned. If the properties for that file are not cached at all, the property will be retrieved
* from the properties file and returned.
*
* <p>NOTE: THIS IS AN EXPENSIVE OPERATION. IT WILL CREATE A DEEP COPY OF THE PROPERTIES AND
* RETURN IT. THAT MEANS IT WILL CREATE AN EXACT REPLICA WITH ALL DATA. THIS IS A PROTECTION TO
