players cannot access a server via domain name when the DNS lookup involves a srv record with a port mapping.

I've verified my test server is accessible in older versions via this setup. The latest client version cannot access the same servers when given the same information.

I've verified all network adapters in my test case have ipv6 disabled.

What I expected to happen was...:

when accessing a server via a nonstandard port via SRV lookup, the client sees a SRV record containing a different port and uses the port defined in the SRV record.

What actually happened was...:
minecraft client does not communicate via the port provided by the srv record and sees no server available.

Steps to Reproduce:
1. set up a minecraft server using a port other than default
2. create a domain mapping and srv record
3. port forward
4. wait for propagation and verify record is accessible
5. verify server is accessible with the port number, e.g. `play.myserver.net:1234`
5. attempt to log in via domain name without port number, e.g. `play.myserver.net`
