metatech commented on SMX4-1245:
--------------------------------
Marco, in your "list" output, the host/fragment relationship is correctly
detected :
[ 64] [Active ] [Created ] [ ] [ 50] activemq-core (5.7.0)
Fragments: 69
[ 69] [Resolved ] [ ] [ ] [ 50] activemq-blueprint (5.7.0)
Hosts: 64
The state is also reported as "GracePeriod", but with a different cause than
this JIRA bug report.
Beware that the Blueprint state can stay in "GracePeriod", even if the bundle
is in "Creating" state (see ARIES-805).
> activemq-broker.xml stays in Blueprint "GracePeriod" state forever

> Project: ServiceMix 4
> Issue Type: Bug
> Environment: ServiceMix 4.3
> Reporter: metatech
>
> In a small proportion of the time (about 20%), during the first start of
> ServiceMix after installation, the bundle "activemq-broker.xml" stays in the
> "GracePeriod" forever (ie no timeout after 5 minutes). It is waiting for a
> namespace handler for the namespace "http://activemq.apache.org/schema/core";,
> which should be exported by the bundle "activemq-blueprint", which is
> declared as a OSGi fragment of the "activemq-core" bundle. When the problem
> occurs, the fragment is not properly attached to the host bundle. See the
> extract of the Karaf console :
> {code}
> [ 46] [Active ] [ ] [ ] [ 60] activemq-core (5.4.2)
> [ 56] [Installed ] [ ] [ ] [ 60] activemq-blueprint
> (5.4.2)
> [ 59] [Active ] [GracePeriod ] [ ] [ 60] activemq-broker.xml
> (0.0.0)
> {code}
> There are no "Hosts:" and "Fragments:" lines.
> The activemq-blueprint stays in "Installed" state instead of "Resolved", and
> cannot be started manually because it is a fragment bundle.
> Proposed short-term workaround (untested) : merge both bundles
> "activemq-core" and "activemq-blueprint".
> Long-term solution : I guess the problem is due to a race condition between
> the starting of the bundles and the discovery of the "host-fragment"
> relationship : maybe a 2-phase mechanism is needed.
