>             Project: Commons Configuration
>          Issue Type: Bug
>    Affects Versions: 1.6
>            Reporter: N Campbell
>
> When two property files are combined using commons config 1.5, the aggregate 
> configuration returns an expected result of 6 entries. If Commons 
> configuration 1.6 or higher is used, the resulting set drops to  which is not 
> expected. 
> The property names include 2, 3 or 4 part names X.Y, X.Y.Z etc and it appears 
> that as of 1.6 if the names are arranged in 2 part, then 3 part etc that the 
> combiner returns the expected result.
> There does not appear to be any release notes etc that would suggest  that 
> this isn't a defect versus an intended implementation change.
