      Description

      This simple part of code demonstrates the NullPointerException in the current code of the MariaDB driver (v1.1.3):

      try {
      Class.forName("org.mariadb.jdbc.Driver");
      String dbUrl = "jdbc:mysql://host:3306/db";
      Connection con = DriverManager.getConnection(dbUrl, "user", "pwd");
      Statement stmt = con.createStatement();
      // do not add any batch entries!
      stmt.executeBatch(); // -> NullPointerException
      con.close();
      }
      catch(Exception ex) {
      ex.printStackTrace();
      }
      
      

      Result:
      java.lang.NullPointerException
      at org.mariadb.jdbc.MySQLStatement.executeBatch(MySQLStatement.java:1121)

      This NullPointerException is raised when the executeBatch is called with no batches added.
