MC-86722Broken RFC 2782 (DNS SRV) conformance
When resolving server location through DNS SRV records, MC ignoring priority and weight, blindly trying the first record returned by query.
Furthermore, it is retrying the search when an attempt is made to connect to a given server that currently marked as available.
Reproduction steps:
Set up your DNS resolution like this:
$ORIGIN example.com.
primary A 127.0.0.1
secondary A <some.fake.ip.address>
_minecraft._tcp.mc SRV 1 5 25565 primary
_minecraft._tcp.mc SRV 5 5 25565 secondary
Start server and client on the same machine.
In client, add "mc.example.com" to the list of servers.
Repeatedly tap "Refresh" button.
Observe the server coming in and out of availability.
When the server listed as "Available", attempt connection.
Observe the connection error with no further explanation.

Is this still a concern in the current Minecraft Snapshot 15w44b or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
It is not a concern. It is an issue.
Nothing has changed.
Still same problem.
Thanks, but found this is a duplicate of MC-49826
Your search-foo was better than mine. I've tried to search before reporting, but found nothing.
