[JBoss JIRA] (WFCORE-1405) Ability to configure a listener to receive management notifications

Brian Stansberry updated WFCORE-1405:
-------------------------------------
Fix Version/s: 3.0.0.Beta1
> Ability to configure a listener to receive management notifications
> -------------------------------------------------------------------
>
> Key: WFCORE-1405
> URL: https://issues.jboss.org/browse/WFCORE-1405
> Project: WildFly Core
> Issue Type: Feature Request
> Components: Domain Management
> Reporter: Brian Stansberry
> Priority: Blocker
> Fix For: 3.0.0.Beta1
>
>
> Provide a means to configure registration of a listener registration for management notifications.
> Users would implement a new NotificationRegistrar interface and register their impl in the configuration, with a management resource created for each configured NotificationRegistrar.
> The interface would be invoked by the kernel during add of the NotificationRegistrar resource (at boot or post-boot if it's added then.)
> The method passes in a ref to a client that subsequently can be used to invoke management ops, and a registry users can use to register listeners for future management notifications.

[JBoss JIRA] (JBJCA-1310) NPE when validating database connection (and the validation failed) if connection pool statistics is enabled
