Additional information: so when I copy and paste the URL `http://localhost:9999/bigdata/sparql?query=SELECT%20*%20where%20%7B%3Fa%20%3Fb%20%3Fc%7D%20LIMIT%2010` into the browser, it spits out valid XML, it just doesn't when the request is made from the GUI, which results in a `net::ERR_FAILED 200`, which I believe is a CORS issue. Also potentially relevant: when the request `SELECT * where {?a ?b ?c} LIMIT 10` is run in the Wikidata Query Service GUI at `localhost:600`, the command-line `./runBlazegraph.sh` output prints the following: 23:12:59.555 [com.bigdata.journal.Journal.executorService47] ERROR com.bigdata.util.concurrent.Haltable IP: UA: -
