MariaDB Connector/J support was added in 1.2.0, but it was a very simple change to support the Java class that the MariaDB Connector/J driver runs under - otherwise, support for MySQL and MariaDB remains largely the same. It is possible that some changes in more recent versions of the MariaDB server are causing incompatibilities. It's definitely worth some more testing. -Nick
