> Some methods of {{CompositeConfiguration}} expect that the in-memory configuration is of type {{BaseConfiguration}} (a configuration of this type is created if no specific in-memory configuration was provided).
> However, there are constructors accepting an arbitrary {{Configuration}} object as in-memory configuration. If here a configuration is specified which does not extend {{BaseConfiguration}}, the casts performed by these methods will fail. The casts should only be performed if possible.
> The following methods are affected:
> * _setListDelimiter()_
> * _setDelimiterParsingDisabled()_
