> In a small proportion of the time (about 20%) of first starting ServiceMix, 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.
