Description

Using camel-quartz in my camel based application (V 2.10.3), I
schedule a backup every day at 19h20 using this expression
from(quartz://backup?cron=0+20+19+?).process(...

the trigger is successfully executed the first day at 19h20, but
failed the next day with this stacktrace.

I scheduled other tasks running every 5 minutes without any errors.

Looking at the code, I understand it can append when endpoints are
removed from the LRU of the camelContext (endoints field from
DefaultCamelContext).
