Capability requirement can be lost if two attributes on same resource reference the same capability --------------------------------------------------------------------------------------------------- Key: WFCORE-3039 URL: https://issues.jboss.org/browse/WFCORE-3039 Project: WildFly Core Issue Type: Bug Components: Domain Management Reporter: Darran Lofthouse Assignee: Brian Stansberry Priority: Critical With the following three commands the server becomes unable to boot due to a missing dependency: - {noformat} /subsystem=elytron:write-attribute(name=initial-providers, value=combined-providers) /subsystem=elytron:undefine-attribute(name=final-providers) /subsystem=elytron/aggregate-providers=combined-providers:remove {noformat} If however I execute :reload after the first two commands, the final command will fail correctly. {noformat} [standalone@localhost:9990 /] /subsystem=elytron/aggregate-providers=combined-providers:remove { "outcome" => "failed", "failure-description" => "WFLYCTL0367: Cannot remove capability 'org.wildfly.security.providers.combined-providers' as it is required by other capabilities: capability 'org.wildfly.security.elytron' requires it for attribute 'initial-providers' at address '/subsystem=elytron'", "rolled-back" => true } {noformat} I am only listing the 'Domain Management' component as I believe the security example is just the reproducer.
