Hi BrainStone, this has been corrected with MariaDB 10.3.1 version (still Alpha).
If you test it with Docker, since a few days, last version 10.3 now default on 10.3.1.

(that's why i've just added 10.3 to test suite : https://travis-ci.org/MariaDB/mariadb-connector-j/builds/270558209 )

If you still want to test 10.3.0, you can use driver, but set the option "useBulkStmts" to false. (Implementation has issue with 10.3.0).
