Carsten Ziegeler commented on SLING-339:
----------------------------------------
When implementing an own job processor, it is advisable to use the
EventUtil#processJob method.
The first implementation will add the acknowledges to this method, so when this
method is used, everything is fine.
The background clean up thread will be enhanced to check for non acknowledge
jobs and mark them as failed. (calling finish with failed value)

> Currently there is no acknowledge that someone is interested in processing a
> job. This results in the problem
> that jobs might end up locked in the repository for ever if there is noone
> interested in processing this kind of
> job.
> This couldbe solved by requiring that a job processor acknowledges the
> receival of a job and thereby indicates that it will process this job. This
> could also be used to deny other processors for this job.
> If a job is not acknowledged during a specified timeout, the job will be
> removed.
