-----------------------------------
Summary: The Discovery module does not work any more after a
ResourceResolverFactory reactivation
Key: SLING-5602
URL: https://issues.apache.org/jira/browse/SLING-5602
Project: Sling
Issue Type: Bug
Components: Extensions
Affects Versions: Discovery Oak 1.2.6
Reporter: Radu Cotescu
Assignee: Stefan Egli
Priority: Blocker
Fix For: Discovery Oak 1.2.8
The Discovery module does not work any more after the Resource Resolver Factory
is reactivated. To reproduce this start the latest launchpad and then:
# go to
http://localhost:8080/system/console/configMgr/org.apache.sling.jcr.resource.internal.JcrResourceResolverFactoryImpl
# click on save (this will trigger the component's reactivation)
# check the error log
