Expected to happen:
When connecting to a server with multiple entries in the SRV record, one should be picked first. If the connection to said hostname fails, another should be tried until a successful connection has been made.
 
Actually happened:
If the connection to the first entry picked fails, no attempts are made to connect to the other entries.
 
Steps to Reproduce:
Set up two servers and an SRV record for _minecraft._tcp.example.com

10 0 25565 main.example.com
20 0 25565 backup.example.com

 
Kill the server at main.example.com.
 
Connect to example.com with minecraft.
 
Observe as the connection fails, and no attempt is made to connect to the backup server.
