> If a provider is reporting new artifacts and these artifacts need to be copied into the local storage (like JCR artifacts), there is a slight change that while the OSGi installer is processing the new artifacts, the same provider is updating the artifacts which then results in a null stored in the internal data objects for the file, although it is still available. The artifact can't be installed anymore as the file is not available.
> This is due to the logic in FileDataStore#createNewDataFile which returns null if the file is already cached.
