-------------------------------------
I don't know if it's this issue or a related issue, but all basic tests as well
as "bin/solr start" now throw the following exception:

> Tracking the key metrics over time is very helpful in understanding the
> cluster and user behavior.
> Currently even basic metrics tracking requires setting up an external system
> and either polling {{/admin/metrics}} or using {{SolrMetricReporter}}-s. The
> advantage of this setup is that these external tools usually provide a lot of
> sophisticated functionality. The downside is that they don't ship out of the
> box with Solr and require additional admin effort to set up.
> Solr could collect some of the key metrics and keep their historical values
> in a round-robin database (eg. using RRD4j) to keep the size of the historic
> data constant (eg. ~64kB per metric), but at the same providing out of the
> box useful insights into the basic system behavior over time. This data could
> be persisted to the {{.system}} collection as blobs, and it could be also
> presented in the Admin UI as graphs.
