Can't insert data more than 254 in sqlite database by java

I am using a java class which allow me to insert data into SQLite database from string. I am inserting the data by a loop. My string have 260 data. When I try to insert those data from string to sqlite database it works fine but stops at the position of 254 every time! Why ?!

for(i = 0; i < 260; i++)
    {
        try {
            Class.forName("org.sqlite.JDBC");
            connection = DriverManager.getConnection("jdbc:sqlite:D:\\new.db");
            java.sql.Statement statement = connection.createStatement();
            statement .executeUpdate("INSERT INTO suggestion (suggesting) VALUES('"+words[i]+"')");
             System.out.println(i + " - " + words[i]);
        } catch (ClassNotFoundException ex) {
            Logger.getLogger(Word.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

Here is the error log from netbeans!
