    Description

      We use MySQL as database, and Ant and JDBC to prepare test databases.
      We recently switched over from commercial MySQL driver, to the MariaDB client. Our main application works fine with the MariaDB client, but when using Ant and JDBC to execute database preparation operations, such as; drop, create, use, MariaDB hangs indefinitely.

      We've tried drop, create database, use database, select * from mysql.user, all hangs forever. (One one occasion our build hang approximately 14 hours over night.)

      This target using MariaDB client, hangs:
      <target name="sql-maria">
      <sql userid="root" password="root" url="jdbc:mysql://localhost/" driver="org.mariadb.jdbc.Driver" classpath="mariadb-client-1.0.0.jar" print="true">
      use my_database;
      </sql>
      </target>

      Output from MySQL in mysqld.sql:
      130114 10:11:07 101 Connect root@localhost on
      101 Query select @@sql_mode
      101 Query set autocommit=0
      101 Query use my_database

      This target using MySQL commercial driver, works fine:
      <target name="sql">
      <sql userid="root" password="root" url="jdbc:mysql://localhost/" driver="com.mysql.jdbc.Driver" classpath="mysql-connector-java-commercial-5.1.13-bin.jar" print="true">
      use my_database;
      </sql>
      </target>
