> Allow shutdown hook registration handling to be customizable
> ------------------------------------------------------------
>
> Key: LOG4J2-868
> URL: https://issues.apache.org/jira/browse/LOG4J2-868
> Project: Log4j 2
> Issue Type: New Feature
> Components: Core
> Affects Versions: 2.0.2
> Reporter: Matt Sicker
> Assignee: Matt Sicker
> Fix For: 2.1
>
>
> Besides the ability to enable or disable the shutdown hook, there should be a ShutdownRegistrationStrategy interface for customizing how to register a shutdown callback in LoggerContext. This will allow application servers to specify their own class that can register the shutdown callback for a LoggerContext.
> To make this really flexible, Log4jContextFactory should be the class that creates the ShutdownRegistrationStrategy.
> The basic idea behind this feature is already implemented. I'd like to make this API a bit better before 2.1 so we aren't stuck with a useless interface later on.
