> If you do shell:new for a class that is not directly known to the shell.command bundle you get a ClassNotFoundException.
> The reason is that the DefaultConverter is used to convert from String to Class which uses the bundle classloader. The shell.commands bundle can not know all possible classes.
> A workaround is the do "dynamic-import org.apache.karaf.shell.commands" to make all packages available to the bundle. This opens a lot of possible problems though. 
> So I think a proper solution would be to use the capabilties to find the bundle that exports the package and use the classloader of this bundle to load the class.
> In case there are multiple versions of the package we could allow to specify a bundle to import the package from or allow to specify a version range for the package.
