"Service factory returned null" after AEM migration from 6.0 to 6.3

[Former Community Member]

Hello experts!

My log is full of "Service factory returned null" errors after migrating AEM 6.0 to 6.3 and updating Java 7 to Java 8.

Here some examples:

	8790	12.12.2017 16:54:24.321 *ERROR* [FelixDispatchQueue] com.day.cq.cq-replication FrameworkEvent ERROR (org.osgi.framework.ServiceException: Service factory returned null. (Component: com.day.cq.replication.impl.OutboxManagerImpl (506)))
	8959	12.12.2017 16:54:24.322 *ERROR* [FelixDispatchQueue] com.day.cq.cq-replication FrameworkEvent ERROR (org.osgi.framework.ServiceException: Service factory returned null. (Component: com.day.cq.replication.impl.transport.RepositoryTransportHandler (507)))

My DS bundle version is:

Version	2.1.0.B001
Bundle Location	launchpad:/WEB-INF/resources/install/9/org.apache.felix.scr-1.8.2.jar

Seems like a general problem. Do you have any ideas why?

Could you check if all the bundles are up properly?

Hey thanks for your reply.

Yes all bundles are running. I read here Apache Felix - Users - Service Factory returned null that updating the org.apache.felix.sc bundle resolved the issue. But mine is already up to date.

I just compared my bundles with the ones of a fresh AEM 6.3 installation and found the following differences:

I don't see anything suspicious here though.

If you build new bundles (using 6.3 dep) - are you seeing this issue

[abhishekagg19]

Are you having any UGC reverse replication related configuration in your AEM?

[smacdonald2008]

This issue does not happen on a fresh install. I suspect the issue is related to an upgrade bug. I recommend opening a ticket for this.
