> Possible ClassCastException in CompositeConfiguration if a special in-memory
> configuration is used
> --------------------------------------------------------------------------------------------------
>
> Key: CONFIGURATION-476
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-476
> Project: Commons Configuration
> Issue Type: Bug
> Affects Versions: 1.7
> Reporter: Oliver Heger
> Assignee: Oliver Heger
> Fix For: 1.8
>
>
> 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()_
