Strange AppVeyor failure in PR

[Stanislav Baiduzhyi]

Good day,

I've created a PR to java-driver project, but AppVeyor build failed for a reason that seems completely unrelated. Could someone please retrigger the build, or teach me how to do it?

Hi Stanislav,

I went ahead and retriggered the build.  It looks like the test that failed was timing oriented:

The test validates that only 1 query was received by the host.  The query  'select cluster_name from system.local' is what the driver sends when it first connects to the host.  The test isn't smart enough to filter out queries like these that it's not interested in (will fix it) and usually this query would have been cleared out of the query log, so it's not related to your change.

Thanks!

Andy
