Subject [jira] [Commented] (FELIX-3334) PreferencesManager can throw NPE after being stopped.
Date Mon, 12 Mar 2012 13:22:39 GMT

    [ https://issues.apache.org/jira/browse/FELIX-3334?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13227505#comment-13227505

Carsten Ziegeler commented on FELIX-3334:

To be honest, i'm not using this implementation very intensively, so changes are that there
are more concurrency issues.
I'm wondering f we need the support for different stores at all or just go with the default
store and are done. So far I haven't heard that someone is using its own store implementation

> PreferencesManager#bundleChanged tries to intercept bundles that are uninstalled. However,
if the PreferencesManager itself is stopped, it does not unregister itself as bundle listener,
causing possible NPEs when other bundles depending on the preferences service are stopped
later on, for example during a shutdown.
> I've got a patch available, will attach it to this issue to be applied.
