I don't understand why getSource throws an Exception when a property can be found in multiple configurations. If the property is not a list or if escaping is disabled then the value from the first Configuration the key is found in will be used. Shouldn't an Exception only be thrown when the value is constructed by merging values from two Configurations? (This only seems to happen if a String with the escape character is present). I'm writing a class that extends CombinedConfiguration and I wanted to changed this behavior so that it works that way but unfortunately findSourceConfiguration is private instead of protected so I can't reimplement getSource without also reimplementing findSourceConfiguration.
The getSource() method was added on behalf of CONFIGURATION-215 [1]. The original request was a bit adapted to come to a more generic solution. IIRC the usage scenario was that you have multiple child configurations with different name spaces and want to uniquely identify the child configuration that added a specific key. If multiple child configurations define the key in question, no unique source can be identified; hence the exception.
Do you propose making findSourceConfiguration() protected? I did not do this in the past because I was not sure whether there would be another use case for this method and I wanted to keep the API lean. But if you need it, I am not against this change.
