--------------------------------------
Summary: Race condition in MapEntries: Resource resolver is
already closed (Error while dispatching observation events for
//*[11111b]@org.apache.sling.jcr.resource.internal.JcrResourceListener
Key: SLING-11498
URL: https://issues.apache.org/jira/browse/SLING-11498
Project: Sling
Issue Type: New Feature
Components: ResourceResolver
Affects Versions: Resource Resolver 1.7.10
Reporter: Henry Kuijpers
It seems that there is a race condition and/or unexpected condition in
MapEntries.
This class also seems to be receiving notifications for events that it does not
seem to be interested in (//*[1111b]@....)
This seems to be somewhat related to SLING-7019 and SLING-4756.
