Fixes #7161.

I know this PR fixes the linked issue. What I really truly absolutely don't know is if it's the correct thing to do :-)

Hmm, the failing test says:

com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host localhost, port 1433 has failed. Error: "Connection refused (Connection refused). Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".

It seems unlikely to me that this could be caused by the change in this PR. Looks more like a flaky test. Is there a way to rerun...?

Thanks @geoand! Should this be in a milestone or something like that? (I don't know, and don't have permissions to set it anyway :-) ) Just wondering.

Ah yes, my bad, I should have added it! Thanks for pointing that out.

Now I'll go and check the other PRs that I merged :P
