----------------------------------------

             Summary: Possibe memory leak when using CombinedConfiguration
                 Key: CONFIGURATION-572
                 URL: https://issues.apache.org/jira/browse/CONFIGURATION-572
             Project: Commons Configuration
          Issue Type: Bug
            Reporter: Rob Walker
            Priority: Minor


We altered our code to use CombinedConfiguration in a more dynamic way and immediately started
to see large memory usage. Looking for a potential leak, we realised we were missing a clear()
when the config objects were done with.

Even with this call in, the leak persisted. It seems that whilst the clear() method cleans
up the object, it doesn't clear the listener list as well. This leaves around stale references
which then never become GC.

Will attach the patch we found worked at curing this
