> Make sure the local console is fully working before the user can type commands

> Key: KARAF-1640
> URL: https://issues.apache.org/jira/browse/KARAF-1640
> Project: Karaf
> Issue Type: Improvement
> Reporter: Christian Schneider
> Assignee: Christian Schneider
> Fix For: 2.3.0, 3.0.0
>
>
> The console bundle starts early as it contains jline, gogo and karaf specific
> console interfaces and tools that all commands need.
> The problem with this is that the user can start typing commands before all
> commands are started. So it can happen that a command is not available at
> that point. This leads to (from the user point of view) errors in completion
> and when executing commands.
> So the idea is to still start the console bundle early but make sure the
> shell is only opened when all commands are started.
> As commands often use blueprint to startup we can not simply check the bundle
> status as it will be active before the commands are activated.
> So one option to improve the situation is to split the shell starting from
> the rest of console and do it in a separate bundle with a high start level.
> So most of the commands would be present. Still because of the blueprint
> startup we could miss some bundles.
> Another option is to start a thread that somehow watches the start of the
> bundles and that opens the shell when all bundles are really active. We could
> use the new status checking from the bundle module that also can watch
> spring-dm and blueprint status. The advantage with this aproach is that we
> could display the live startup status while waiting.
> We could also allow the user to press e.g. enter to open the console at any
> point.
> So for example we could show something like this:
> Karaf startup ...
> Press Enter to open a shell now
> Bundles started (11/78), 3 failures
