Hi,

The current implementation of ConfigurationWatchList.convertToFile returns null when the URL type is not file.
Due to this automatic reloading on change of configuration does not work in OSGi bundles.

This problem occurs even if you use a fragment. As in any case, the logback.xml file will be recognized as
bundleresource type and not as file type. This is necessary as the logback.xml config file is recognized during
the start up time. So, it creates confusion as the file is found first time around and then the reloading does not 
occur. And, this is not mentioned in the documentation either. Given that logback has a p2 repository for OSGi 
support, IMHO this feature is a must. 

BTW I would love to contribute this feature.

Ashwin
