> While using the file system resource provider in a development scenario, with sample content in JSON format, it turned out that the resource provider never recovered from a syntax error in a JSON file, even after the error was fixed. Only after restarting the bundle the resource was ok again. The same behaviour was then also verified with the FileVault XML format.
> The scenario was observed on a Sling system with multiple listeners for resource change events, which access the changed resource right after the change. It seems that there is a race in the way {{FileMonitor}} updates the {{ContentFileCache}} ans sends events.
> Sending the events after removing the cache-entry seems to fix the problem.
