I can reproduce the issue.
I think it might be a bug in the resolver.
What I found:
Camel commands import this package:
(&(osgi.wiring.package=org.apache.karaf.shell.console)(version>=3.0.0)(!(version>=5.0.0)))
The exported packages show this:
org.apache.karaf.shell.console │
2.3.0 │ 42 │ org.apache.karaf.shell.console
org.apache.karaf.shell.console │
4.1.0 │ 42 │ org.apache.karaf.shell.console
So the package is exported in two versions. The version 2.3.0 would not
match the range camel imports, the 4.1.0 version would match it.
I suspect that the resolver behaves differently depending on which
version it checks first. If it checks the 4.1.0 first it works, if it
checks the 2.1.0 version first it fails.
I guess it should check both versions and take the working one but
apparently it does not.
Unfortunately I do not know the implementation well enough to check or
fix this but maybe it helps Guillaume to find the issue :-)

The commands are available and work. But after Karaf restart they are no more
available and the log contains following error:

The same happens with other 3rd party commands, e.g:
karaf@root()> feature:repo-add activemq 5.15.0-SNAPSHOT
21:39:14
Adding feature url
mvn:org.apache.activemq/activemq-karaf/5.15.0-SNAPSHOT/xml/features
karaf@root()> feature:install activemq-broker-noweb
21:39:26
karaf@root()> activemq
21:39:37
activemq activemq:bstat activemq:consumer activemq:list
activemq:producer activemq:query
activemq:browse activemq:bstat activemq:dstat activemq:list
activemq:purge activemq:query
activemq:browse activemq:consumer activemq:dstat
activemq:producer activemq:purge
Is this the same problem you have mentioned in this thread?
Kindly regards

2. Shell command issue
Several projects providing shell commands (like Camel, ActiveMQ, ...) directly use
jline dependency. It's pretty bad (they should use the Karaf "wrapper), and, as
Karaf 4.1.x now uses JLine 3.x, those commands don't work in Karaf 4.1.x.
Here, we have two solutions:
2.1. We create the jline "2.x" compliant packages in Karaf (in a bundle as part
of the shell-compat feature for instance). It's only a workaround but should fix the
issue.
2.2. jline 3.x can provide a "compat" bundle with the jline 2.x packages name,
wrapping the jline 3.x ones. It's probably the most elegant solution, but it's require a
new jline 3.x release.
