> [Java Broker] [ACL] A recovered RuleBasedVirtualHostAccessControlProvider

> Key: QPID-7934
> URL: https://issues.apache.org/jira/browse/QPID-7934
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: qpid-java-6.1, qpid-java-6.1.4
> Reporter: Keith Wall
> Assignee: Keith Wall
> Priority: Minor
> Fix For: qpid-java-broker-7.0.0
>
>
> A recovered {{RuleBasedVirtualHostAccessControlProvider}} doesn’t tell its
> virtualhost about changes to itself, so the virtualhost doesn’t react to
> changes in its state (i.e. the rule-set). This issue exists on the normal
> Broker start-up path. It means that if the user attempts to change a
> rule-set the changes are not applied.
> If a new RuleBasedVirtualHostAccessControlProvider is added, changes made to
> it are reported properly to the VirtualHost. (This is why
> {{VirtualHostAccessControlProviderRestTest}} does not fail).
> The issue is that {{AbstractVirtualHost#postResolveChildren}} fails to add
> state listeners to existing {{VirtualHostAccessControlProviders}}. The same
> issue applies on the virtualhost restart path (much like QPID-7933).
> There is a second problem that lies behind the first. If you fix
> #postResolveChildren to install the listener on the existing VHACP, you find
> that the VH still fails to update its ACL controller state probably after
> changes to the provider. This problem is that
> {{AbstractVirtualHost#updateAccessControl}} gets called (by the super call at
> line AbstractCommonRuleBasedAccessControlProvider.java:70) before
> {{AbstractLegacyAccessControlProvider#recreateAccessController}} on the
> following line so the VH continues to stale a stale controller.
> The user can work around the problem by restarting the Broker.
