We shouldn't generate a massive error like this.
Ideally we should just list the plugins and then highlight the incompatibility, like this;
# /usr/share/elasticsearch/bin/elasticsearch-plugin list
x-pack@5.0.0-beta1 - INCOMPATIBLE PLUGIN, PLEASE UPGRADE
But if not, then just having a plain text response like Plugin [PLUGINNAME] is incompatible with Elasticsearch [VERSIONNOW]. Was designed for version [VERSIONPAST] would be great.
This is what KB does after upgrading;
# /usr/share/kibana/bin/kibana-plugin list
timelion@5.0.0-alpha5
x-pack@5.0.0-alpha5-SNAPSHOT
At this point, I'd still need to upgrade, though it doesn't stacktrace and could have info on the incompatibilities to make things clear.
