Subject [jira] [Created] (CONFIGURATION-476) Possible ClassCastException in CompositeConfiguration if a special in-memory configuration is used
Date Sun, 15 Jan 2012 21:21:39 GMT
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


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()_
