metatech updated SMX4-1245:
---------------------------
Description:
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.
