Javadoc
Utility method which loads the given properties file and returns a
Properties object containing the key,value pairs in that file.
The properties files should be in the class path as this method looks
to the thread context class loader (TCL) to locate the resource. If the
TCL is a URLClassLoader the findResource(String) method is first tried.
If this fails or the TCL is not a URLClassLoader getResource(String) is
tried.
