             Summary: ReloadingCombinedConfigurationBuilder needs to clear the reloadingController on resetParameters()
                 Key: CONFIGURATION-786
                 URL: https://issues.apache.org/jira/browse/CONFIGURATION-786
             Project: Commons Configuration
          Issue Type: Bug
          Components: File reloading
    Affects Versions: 2.6
            Reporter: David Citron


Modifying the _configuration definition file_ causes {{CombinedConfigurationBuilder.resetParameters()}} to be called. This cleans up and clears the {{sourceData}} variable which causes the next invocation of {{initResultInstance()}} to create new child {{ConfigurationBuilder}}s.

However, {{ReloadingCombinedConfigurationBuilder.reloadingController}} is not cleared (set to null) and, as such, reloading stops working until a full restart.

I have worked around this by using reflection to set {{ReloadingCombinedConfigurationBuilder.reloadingController}} to null when {{resetParameters()}} is called, but perhaps further thought is required vis-a-vis a fix because re-creating the {{reloadingController }} means that any attached {{PeriodicReloadingTrigger}}s need to be shut down and re-created too (which is what I'm currently doing to make all this work).
