Description:
In Connector/J 5.1.39 the deprecate-EOF feature was implemented.

https://github.com/mysql/mysql-connector-j/commit/e8d178fb9a7827057c8824e96fa82440f6342a60

If you connect with Connector/J 5.1.38 or earlier to MySQL Server 5.7.17 then Connector/J doesn't set the deprecate-eof flag.

Then the server is expected to send EOF packets, but that doesn't happen.

How to repeat:
Connect with Connector/J 5.1.38 and 5.1.41 and
1. Check the EOF-deprecation flag
2. Check if EOF packets are present
