Folks, an explicit undeploy operation should remove state that otherwise needs to survive server restart. How can I distinguish between these two cases in a DUP? cheers --thomas

An OSGi bundle has a persistent storage area (see standalone/data/osgi-store). When a bundle gets uninstalled the persistent storage is supposed to get removed.

On server shutdown we also undeploy every bundle. In this case however I don't want to remove the bundle's storage area. Currently, we never remove the storage area (https://issues.jboss.org/browse/AS7-5948).

IMO, clearing the storage area should perhaps be outside of the DUPs, so that the undeploy just functions the same irrespective of whether it's a undeploy or shutdown. -Jaikiran > On server shutdown we also undeploy every bundle.

The org.jboss.as.controller.ControlledProcessStateService service is meant to be used for this kind of thing. But, the case of stopping via a soft kill instead of a management op isn't properly handled. For that, someone would need to do https://issues.jboss.org/browse/AS7-4492 There was a dev list thread in April related to this; it's linked on the JIRA.
