CFSCHEDULE not working after second update


I am using Railo (no specific need to update to Lucee just yet),
and have come across a strange issue.

I create a task using the cfschedule tag with action = update (via
cfscript, if that matters), set to run one minute after execution. If I
call this function once,
it works perfectly fine.

The second time this function is called, to update the timestamp of the
existing task, the task expires, but the URL is never called. Nothing shows
in WEB-INF/railo/logs/scheduler.log
with the level set to TRACE either, other than the initial “schedule task
… first execution runs at …” line.

Same thing happens if I to cfschedule action = delete beforehand as well.

Does anyone know if this a bug in that particular version of Railo?
