-------------------------------------
Summary: File system resource provider may never recover from
JSON/XML syntax errors
Key: SLING-7370
URL: https://issues.apache.org/jira/browse/SLING-7370
Project: Sling
Issue Type: Bug
Components: Commons
Affects Versions: File System Resource Provider 2.1.8
Reporter: Julian Sedding
Priority: Minor
Fix For: File System Resource Provider 2.1.10
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 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.
