The Karaf issue that caused this should be fixed in Karaf 4.0.8:
https://issues.apache.org/jira/browse/KARAF-4762
This should be resolved by the upgrade to Karaf 4.0.8 on OpenNMS and Minion. PR merged, marking as fixed.

Just ran into this again, I'll attach the entire log.

There is a note in the Apache Karaf 4.1.0 release notes about this issue so it will probably only be resolved by upgrading Karaf.

Reducing to Major since this is a transient error.

I've been unable to reproduce this in any consistent way. The 'mvn' protocol handler, is provided by the 'pax-url-aether' bundle, which is loaded by default.
The KarafExtender modifies the configuration of the 'pax-url-aether' bundle at startup, configuring the additional repositories found in the $MINION_HOME/repositories folder. This should trigger an update, https://github.com/ops4j/org.ops4j.pax.url/blob/url-2.4.7/pax-url-aether/src/main/java/org/ops4j/pax/url/mvn/internal/Activator.java, but the 'mvn' handler should remain available.
I've added some additional logging statements in https://github.com/OpenNMS/opennms/commit/388722cb4ff9bc69e86406017532348236c82ed2, so we can better quantify when this happens.
