@wborn, I could need some help.

Karaf 4.4.8 reached RC1 today, there will be a RC2 tomorrow.
It have patches for all OH repositories in place, the demo app is starting.

Though, there is one error on distro I am struggling with....

I am a bit stuck with that. Any recommendation?
Karaf moved from Java1.8 min to Java 11, could this be related?

Fixed the issue above by adding <javase>${oh.java.version}</javase>.
Now testing distro with 4.4.8 🥳

Besides those strange warnings in the log,

23:20:37.461 [WARN ] [nternal.config.MavenConfigurationImpl] - Location C:/Users/hf/.m2/settings.xml is not accessible (incorrect value for option "settings")
23:20:37.461 [WARN ] [nternal.config.MavenConfigurationImpl] - Location null/conf/settings.xml is not accessible (incorrect value for option "settings")

23:20:37.462 [WARN ] [nternal.config.MavenConfigurationImpl] - Location C:/Users/hf/.m2/settings-security.xml is not accessible (incorrect value for option "security")

everything seems to work fine 🎉

UI is working, plugin installation is fine. Bundle listing looks great!!!

The log issue will be fixed in RC2 of Karaf 4.4.8.
https://issues.apache.org/jira/browse/KARAF-7995

So it looks like we are ready once Karaf is released! Maybe the modularisation of osgi imports should be discussed. I will add a comment in core repo PR.
