Just found the jira patch attachment doesn't work properly, so even you select the "Grant Apache License" radio button, still can't see the Apache feather icon with the attachment, this is the Apache Jira issue.
Back to your patch, just one thing, webconsole/features/src/main/java/org/apache/karaf/webconsole/features/ExtendedFeature.java implements Feature, but you didn't add new hasVersion() method for that class which cause compilation error. So next time when you attach patch, you need ensure it doesn't break any compilation and tests.
I just add that minor change and will apply your patch soon.
Thanks for the patch.
