Description
Steps to reproduce
- Start a Jetty/HSQL demo instance (I've tested with the Standard Flavor Pre-installed)
- Observe the XWiki logs
Expected results
No (other) warnings are displayed.
Actual results
The following warnings are displayed in XWiki console:
2026-09-16 15:24:46,635 [task-manager-consumer] WARN ateXarObjectPropertySerializer - Failed to parse date [Tue Jun 13 14:29:31 CEST 2017] using format [yyyy-MM-dd HH:mm:ss.S]. Trying again with format [EEE MMM d HH:mm:ss z yyyy]. 2026-09-16 15:24:46,667 [task-manager-consumer] WARN ateXarObjectPropertySerializer - Failed to parse date [Tue Jun 13 14:29:31 CEST 2017] using format [yyyy-MM-dd HH:mm:ss.S]. Trying again with format [EEE MMM d HH:mm:ss z yyyy]. 2026-09-16 15:24:46,681 [task-manager-consumer] WARN ateXarObjectPropertySerializer - Failed to parse date [Tue Jun 13 14:29:31 CEST 2017] using format [yyyy-MM-dd HH:mm:ss.S]. Trying again with format [EEE MMM d HH:mm:ss z yyyy].
The warnings were reproduced also when importing a XAR, but it seems it doesn't reproduce consistently more than when just starting the XWiki instance.
Also, it seems the warning couldn't be reproduced on XWiki 17.10.12 or 18.4.5 (tried multiple instance start-ups), but again, I couldn't find a consistent way to reproduce them.
