Philipp Marx created SLING-2791:
-----------------------------------

             Summary: No way for graceful server shutdown
                 Key: SLING-2791
                 URL: https://issues.apache.org/jira/browse/SLING-2791
             Project: Sling
          Issue Type: Bug
          Components: Launchpad
    Affects Versions: Launchpad Base 2.5.0
            Reporter: Philipp Marx
            Priority: Minor


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.
