Karaf `framework.BundleException` on bin/karaf on macos

Question

I installed karaf on my mac for the second time now. The first time I couldn't get the console to connect whenever I would start the runtime (bin/karaf and bin/start/stop) and nada. bin/client wouldn't connect either. After uninstalling and installing v4.3.6 and then v.4.2.15, I now get the following error whenever trying to fire up karaf:

Error installing bundle listed in startup.properties with url: mvn:org.apache.karaf.features/org.apache.karaf.features.extension/4.2.15 and startlevel: 1

I've tried setting the org.apache.karaf.features.extension to other levels, and have tried other versions of of the same; nothing works.

My startup.properties looks like this:

# Bundles to be started on startup, with startlevel
mvn\:org.apache.karaf.features/org.apache.karaf.features.extension/4.2.15 = 1
mvn\:org.apache.karaf.services/org.apache.karaf.services.eventadmin/4.2.15 = 5

mvn\:org.apache.felix/org.apache.felix.fileinstall/3.7.4 = 11
mvn\:org.apache.karaf.features/org.apache.karaf.features.core/4.2.15 = 15

I am using JDK 11

Does anyone know what I can do to fix this and get karaf running?
