Subject [jira] [Commented] (ARIES-1084) Subsystem : Failure on restart after framework crash
Date Mon, 24 Aug 2015 14:22:47 GMT

    [ https://issues.apache.org/jira/browse/ARIES-1084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14709362#comment-14709362
] 

Alexandre Roman commented on ARIES-1084:
----------------------------------------

I confirm this issue.

As a workaround, I update all DEPLOYMENT.MF files and set the "AriesSubsystem-State" value
to RESOLVED before the framework is started.
All subsystems are now started, whether the JVM previously crashed or was properly stopped.

> Situation : I set up OSGi framework, installed Aries subsystem (and all required bundles),
installed a single trivial feature subsystem containing a single bundle resource. All worked
as expected in normal operation with install/start/stop/uninstall operations working as described
in section 134.14 of the OSGi Enterprise Release 5 spec. Starting and stopping the framework
started and stopped installed subsystem's bundle as expected.
> Problem : When the framework is not closed down gracefully (say JVM crash) the subsystem's
bundle does not restart. The proximate cause of this appears to be that...
>     * The state for each subsystem is persisted in the DEPLOYMENT.MF file, under the
header "AriesSubsystem-State", stored in the Aries subsystem bundle's data storage area.
>     * The state is changed between RESOLVED and ACTIVE (and back again) as the bundle
is started and stopped in a gracefully way.
>     * A JVM crash leaves the "AriesSubsystem-State" value in the file as ACTIVE for both
root and installed subsystem.
>     * Upon restart the my feature subsystem's resource bundle is no longer started as
Aries (presumably) assumes it is already ACTIVE.
> I'm fairly sure that the "AriesSubsystem-State" header is causing the problem because
hand editing it in both root and installed DEPLOYMENT.MF files back to 'RESOLVED' prior to
starting the framework solves the problem.
