     [ https://issues.apache.org/jira/browse/SLING-2791?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Felix Meschberger updated SLING-2791:
-------------------------------------

    Attachment: SLING-2791.patch

Proposed patch.

Adds new -n command line option to prevent installation of a shutdown hook.

Adds support for a new system/configuration property sling.shutdown.hook: If set to true or not set at all, the hook is installed, otherwise the hook is not installed.

> The main class of the launchpad-base will register a shutdown hook on the JVM to tear down the felix framework properly (Framework#shutdown). There are certain situation where a client wants to have a different behaviour, i.e. to implement a graceful server shutdown.
> In Felix itself you can set the "felix.shutdown.hook=false" to prevent Felix from registering its own shutdown hook. It would be great if Sling would provide the same functionality.
> I have already a patch in place which will search for the same property as Felix and in case this is set to true will not create its own shutdown hook but will rely on the client to properly shutdown the framework. I know there are more actions which Sling is doing upon JVM shutdown but since there is also a listener on the Framework shutdown itself these actions will still be performed.
