Commons Configuration keeps the timestamp of the last file check. On 
accessing a property (by calling getString(), getInt(), etc), the file 
is checked again if a specified delay is elapsed since the last check. 
Of course the configuration is not reloaded after this delay if the file 
didn't change.
