Karaf Service Reference Manager returning actual instance and some
times not updating re-registered instance
Hi Karaf team,
We are using below karaf configuration. Our karaf container version:2.3.2
file : src/main/resources/OSGI-INF/blueprint/config.xml of a maven project
which gets into target jar OSGI-INF folder correctly
<reference id="httpService" interface="test.HttpService" />
<bean id="clientService" class="test.Activator"
init-method="start" destroy-method="stop">
<property name="httpService" ref="httpService" />
</bean>
The issue we are observing
1) When we print httpService in test.Activator class we are seeing the same
instance that is actually registered by plugin having the implementation
class.
i.e ObjectId printed by toString() method at the time of registration is
same as
ObjectId printed by toString() method in a plugin which gets this using
reference Manager (test.Activator class)
is this expected, if not expected can you suggest where it could have gone
wrong?
2) Another issue is when a httpService is re registered by the plugin . the
plugin which uses it using blueprint
managed Service is not getting the updated instance.
for e.g 1) httpService@111 registered initially
httpService@111 is seen in plugin using the httpService
using blue print managed Services.
2) A new instance httpService@222 registered now (unregistered
old one i.e httpService@111)
but still httpService@111 is seen in plugin using the
httpService using blue print managed Services.
Please let us know the expected time it will be reflected to plugin using
this service via blue print managed service, also let us know if there is a
way we can control this time or see it quickly or block the plugin using
this service to execute any other methods on it.
Please let us know your suggestions

Agree, it's just to know if the new blueprint version fix your issue or not.
I will review your questions in details anyway.

Hi,
could you try the same on 3.0.0-SNAPSHOT (with the new blueprint release) ?
