hasWarnings is set:

https://github.com/MariaDB/mariadb-connector-j/blob/master/src/main/java/org/mariadb/jdbc/internal/protocol/AbstractConnectProtocol.java#L745


Its used here:

https://github.com/MariaDB/mariadb-connector-j/blob/master/src/main/java/org/mariadb/jdbc/MariaDbConnection.java#L827

I suspect the bug is warningsCleared has a implicit default of false in
the above class.

As a workaround check, call reenableWarnings() before getWarnings().
