We're using the camel quartz component (camel version 2.9.0 and quartz in
version 1.8.5) to trigger some jobs once a day. The routes are looking
similar to this:
from("quartz://aendHistNaechtlicherLauf?cron=0+0+23+*+*+?+*")
.routeId(aendHistNaechtlicherLauf)
.to("bean:aBean?method=aMethod(${header.fireTime})");
BTW: We have only one camel-context.
The problem is: On the first day when the application was started the routes
are running perfect, but on the next day we are getting this exception:
ERROR | 2012-12-05 23:00:00,003 | |

We belive that this error occurs because the gc deletes the endpoint
reference stored in the LRUSoftCache of EndpointRegistry. Shouldn't it be
possible that the quartz-component recreates a endpoint, when the
EndpointRegistry stores only SoftReferences? In this case the tigger should
be deleted, shouldn't it?. Elsewise there has to be a hard reference between
entpoint and trigger, so the gc can't free the endpoint reference.
Has somebody a solution or an idea why this error occurs?
