Marius Petria created SLING-4853:
------------------------------------
Summary: JobManager.findJobs should skip items that have been
removed during the call
Key: SLING-4853
URL: https://issues.apache.org/jira/browse/SLING-4853
Project: Sling
Issue Type: Bug
Components: Extensions
Reporter: Marius Petria
Sometimes under high load the iteration over job nodes can fail [1] because the
nodes could be already processed and removed. We could by more fault tolerant
when reading a resource and just skip it in case of failure.
