Subject [jira] [Created] (KARAF-6181) ManagedServiceFactory does not work reliably anymore
Date Tue, 05 Mar 2019 13:46:00 GMT
Markus von Rüden created KARAF-6181:
---------------------------------------

             Summary: ManagedServiceFactory does not work reliably anymore 
                 Key: KARAF-6181
                 URL: https://issues.apache.org/jira/browse/KARAF-6181
             Project: Karaf
          Issue Type: Bug
    Affects Versions: 4.2.3, 4.2.2
         Environment: Mac OS X, Apache Karaf 4.2.2/4.2.3, Java 8
            Reporter: Markus von Rüden


It seems that the *ManagedServiceFactory* in combination with *service.pid* does not work
reliably anymore with Apache Karaf 4.2.3.

*The Problem*

Registering a *ManagedServiceFactory* with a provided *service.pid* does no longer invoke
the "updated(...)" method ** even when it should. 

*How to Reproduce*

I created a simple example project, where a *ManagedServiceFactory* service is exposed with
*service.pid=org.opennms.dummy.services*

The service simply prints out if a service with the pid managed by the factory was created/updated/deleted

In order to help narrowing down the problem, here is how to reproduce it
 
 * Checkout the [example repository|https://github.com/mvrueden/karaf-managed-service-factory-example]
 * Build the code with {{mvn clean install}}
 * Download latest Apache Karaf 4.2.3 Distribution from [here|http://www.apache.org/dyn/closer.lua/karaf/4.2.3/apache-karaf-4.2.3.tar.gz].
 * Extract the archive
 * Start the container {{./bin/karaf}}
 * Install {{aries-blueprint}}: {{feature:install aries-blueprint}}
 * Install the bundle: {{install -s mvn:org.opennms.dummy/managed-service-factory/1.0-SNAPSHOT}}
 * Verify via {{list}}
 * Now add some configuration files, e.g.

{code}
config:edit org.opennms.dummy.services-1
config:property-set key value
config:update
 {code}

If you check the logs via {{log:tail}} you can see, that only some or none are actually printed.
In my case 2 of 5 were printed. However if I do a {{config:list}} all configs are listed,
but only a few (the printed ones) have a factoryPid.

Restarting the container also did not work.
However, uninstalling the bundle and re-installing it, will work.

I was able to confirm this for 4.2.2 as well. In 4.1.5 it still works as expected.

Please let me know if there is anything I can do to help resolving this.
