> QuartzEndpoint custom calendar name collision when multiple routes use
> customCalendar
> -------------------------------------------------------------------------------------

> Key: CAMEL-24055
> URL: https://issues.apache.org/jira/browse/CAMEL-24055
> Project: Camel
> Issue Type: Bug
> Components: camel-quartz
> Affects Versions: 4.x
> Reporter: Prasanth Ganesh Rao
> Priority: Major
> Attachments: QuartzCustomCalendarCollisionTest.java
>
>
> When two or more Quartz routes in the same CamelContext are configured with a
> customCalendar, the second route silently overwrites the first route's
> calendar in the shared Quartz scheduler.
> *Root cause:*
> QuartzEndpoint.doStart() registers every custom calendar under the hardcoded
> name "CamelQuartzCustomCalendar"
> (QuartzConstants.QUARTZ_CAMEL_CUSTOM_CALENDAR):
> {{scheduler.addCalendar("CamelQuartzCustomCalendar", customCalendar, true,
> false);}}
> The replace=true flag causes the second addCalendar() call to silently
> overwrite the first. Since all triggers are also wired to the same name via
> modifiedByCalendar("CamelQuartzCustomCalendar"), every trigger ends up
> governed by whichever calendar registered last — not the one intended for it.
> *Example:*
> {{// Route A: fires at most once per day (30-second recurrence calendar)}}
> {{{}from("quartz://FrequentTimer?customCalendar=#frequentCalendar&cron=0/2 *
> * * * ?").to("mock:a");{}}}{{{}// Route B: always-open daily calendar —
> overwrites FrequentTimer's calendar{}}}
> {{from("quartz://DailyTimer?customCalendar=#dailyCalendar&cron=0/2 * * * *
> ?").to("mock:b");}}
> After startup, FrequentTimer fires every 2 seconds instead of being
> suppressed, because its trigger now references DailyTimer's always-open
> calendar.
