------------------------------------------------------------------
Just to clarify, the above comment is from a second user experiencing the same
issue, not the original reporter.
Also, the original steps to recreate use the stock karaf distribution, not a
custom one, and involve deploying a single bundle into the deploy folder, so
I'm not sure how it can be a problem specific to the user's distribution or
deployment technique...
Also, it has been observed on both Windows and Linux, although it doesn't
happen always (some race condition is involved).

> Key: KARAF-6210
> URL: https://issues.apache.org/jira/browse/KARAF-6210
> Project: Karaf
> Issue Type: Bug
> Components: karaf
> Affects Versions: 4.2.4
> Environment: Stock Karaf 4.2.4 on Windows 10 with latest Oracle JDK 8.
> Reporter: Amichai Rothman
> Assignee: Jean-Baptiste Onofré
> Priority: Major
> Attachments: karaf_command_not_found.log
>
>
> When starting karaf using equinox and some bundle in the deploy folder, many
> shell commands (such as bundle:* and others) are not recognized, and the log
> shows NoClassDefFoundError: org/apache/karaf/shell/api/action/Action. Some
> commands don't work, but others (e.g. shell:*) do.
> This happens consistently on Windows 10, but not on Linux, not sure why.
>
> Steps to recreate:
> 1. Extract stock Karaf 4.2.4.
> 2. In etc/config.properties change karaf.framework=felix to
> karaf.framework=equinox.
> 3. Place org.apache.aries.transaction.blueprint-2.2.0.jar (from maven) in
> deploy folder. This is not the only bundle it happens with, just a public one
> I found for this example. From several I tried, some recreated the issue and
> some did not. The bundle is not resolved due to missing dependencies.
> 4. Start Karaf.
> 5. Try to run bundle:list and it'll say command not found. Or look at the
> karaf log and see "java.lang.NoClassDefFoundError:
> org/apache/karaf/shell/api/action/Action". Use shell completion to see that
> some commands are available but others are not.
