I just tested on Karaf 4.3.0 with Camel 3.7.0, and it works fine for me:
karaf@root()> camel:route-list
Context Route Status Total # Failed #
Inflight # Uptime
------- ----- ------ ------- --------
---------- ------
camel-1 test Started 1 0
0 2s492ms
karaf@root()> info
Karaf
Karaf version 4.3.0

If using streams then it's recommended to enable stream caching. See more
details at http://camel.apache.org/stream-caching.html

I think JMX is not enabled in your case. Can you try with JMX enabled ?
Thanks,
