Description

Currently there is no way to interrupt Job that was created by Quartz because of

//org.apache.camel.component.quartz2.QuartzComponent
protected void doStop() throws Exception {
        super.doStop();

        if (scheduler != null) {
            AtomicInteger number = (AtomicInteger) scheduler.getContext().get(QuartzConstants.QUARTZ_CAMEL_JOBS_COUNT);
            if (number != null && number.get() > 0) {
                LOG.info("Cannot shutdown scheduler: " + scheduler.getSchedulerName() + " as there are still " + number.get() + " jobs registered.");
            } else {
                LOG.info("Shutting down scheduler. (will wait for all jobs to complete first.)");
                scheduler.shutdown(true);
                scheduler = null;
            }
        }
    }

Is this by design or it is really broken compatibility with Quartz. There is undocumented option in Quartz that you can interrupt Job:
