-----------------------------------

             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
