There’s now a pull request for updating Karaf from 4.1.5 to 4.2.1.
Upgrading Karaf brings a lot of bugfixes and improvements (see Karaf release notes).
With the upgrade Karaf will also support Java 9 and 10.
It would be great if some of you can help out testing the upgrade and find issues before they hit people using the 2.4.0-SNAPSHOT version!
You can download the test artifacts with Karaf 4.2.1 from:
I’ve also created some Docker images using this Karaf 4.2.1 test release, for the tags see:
