MariaDB Connector bug with bulk insert ?

I'm new to MariaDB and testing with some applications. Yesterday I met a wired bug. When I'm using bulk insert with MariaDB connector 1.3.4, following errors occur. (Ubuntu 14.4 and MariaDB 10.1.11)

When I replace the connector driver with 'MySQL connector', It works fine. The reference Q&A was http://stackoverflow.com/questions/18693800/mariadb-jdbc-connection-fails-during-bulk-inserts

The reason that I call this bug is wired was, with same mariadb connector I haven't met bug in any other systems, Mac/Centos 6. Even more another ubuntu system MariaDB 10.1.10 with same driver, no error occurs.

works fine: Linux ubuntu 3.13.0-34-generic #60-Ubuntu SMP Wed Aug 13 15:45:27 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux Error occurred system: No LSB modules are available.
