> The reason for this issue is that the plugin registration in {{ext/plugins.txt}} file is not cleaned up and so the console tries to load it on startup. Normally you would {{:plugin unuse tinkerpop:spark}} prior to the {{:uninstall}} to make sure the cleanup worked properly.
> To fix this problem, {{:uninstall}} should just remove the registration the same way that {{:plugin unuse}} would.
