Hi all!
I'm upgrading my software, which was deployed in top of Karaf 2.2.11, to
Karaf 3.0.0 version. I'm almost finished with the upgrade, but I'm having
some strange problems when starting specific bundles.
I publish my OSGI services via blueprint. I also use dOSGI to expose my
services through WS like this:
*<bean id="vcpeNetworkManager"
class="org.opennaas.extensions.vcpe.manager.VCPENetworkManager"
destroy-method="destroy"/><service ref="vcpeNetworkManager"
interface="org.opennaas.extensions.vcpe.manager.IVCPENetworkManager">
<service-properties> <!-- Rest --> <entry
key="service.exported.interfaces" value="*"/> <entry
key="service.exported.configs" value="org.apache.cxf.rs
<http://org.apache.cxf.rs>"/> <entry
key="service.exported.intents" value="HTTP"/> <entry
key="org.apache.cxf.rs.httpservice.context"
value="${ws.rest.url}/vcpenetwork"/> <entry
key="org.apache.cxf.rs.address" value="/"/> <entry
key="org.apache.cxf.httpservice.requirefilter" value="true"/>
</service-properties></service>*
In order to get the value of the ${ws.rest.url} property, I added the
property-placeholder feature provided by blueprint-cm:
*<cm:property-placeholder persistent-id="org.opennaas"
update-strategy="reload" />*
It works perfectly, but when I install this bundle (and all of them
declaring this placeholder) the services declared in the blueprint are
published are unpublished rrepeatedly for a while. For example, here you
can find an extract of my log file:
16:26:16,246 INFO | xtender: 3 | .manager.*VCPENetworkManager* | Starting
VCPENetworkManager
16:26:16,256 INFO | hread-3624 | .manager.*VCPENetworkManager* | Stopping
VCPENetworkManager
16:26:16,279 INFO | xtender: 1 | .manager.*VCPENetworkManager* | Starting

16:26:16,342 INFO | hread-3630 | .manager.*VCPENetworkManager* | Stopping
VCPENetworkManager

VCPENetworkManager
16:26:16,396 INFO | hread-3632 | .manager.*VCPENetworkManager* | Stopping
VCPENetworkManager
I suggest it has something to do with blueprint-cm because I see this
behaviour only in bundles with the property-placeholder declaration in
blueprint.
Could it be possible? If not, any idea on what could be happening?
Thanks!
