org.apache.karaf.config.core (24): Error while creating extension

Has anyone seen this at Karaf startup and understands what the cause is?

Just looking at MetaServiceCaller.withMetaTypeService(), "ref" could be null but the code does not handle that.

The system runs at a customer, so I cannot manually debug, the only option is essentially to restart Karaf.
Is the effect of this issue that the local console will not work?

Did you try a manual refresh when it happens ?

Re: org.apache.karaf.config.core (24): Error while creating extension

Posted by Jean-Baptiste Onofré <jb...@nanthrax.net>.

Yes, it's rarely null for the service reference, but you are right, we
should improve the code to fallback when it's null.

Can you please create a Jira, I will tackle that ?

Sorry about that.

Regards
JB
