Subject Re: Failing to uninstall a feature marked as not required
Date Fri, 19 Jan 2018 07:35:39 GMT
That's the expected behavior.
The feature:install really means "require this feature" while uninstall
means "do not require this feature anymore".
The features management commands won't allow you to let Karaf in an
"unstable" state, so if you want to perform such operations, you'd have to
do that using the bundle commands instead.
Given this was a bit confusing, please raise a JIRA issue so that we can
improve the user interaction and display better error messages.
