Does the log help? Anything else I can do to move this forward? Something you'd like me to
try? breakpoint anywhere?

>                 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:*)
> 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.
