Error when making connection: You have an error in your SQL syntax;

Question

I'm getting this error when trying to make a simple Database Connection:
SQLException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '????????????????????????????????' at line 1
SQLState: 42000
VendorError: 1064
I tried a different driver and got the same error with more "?"s in the "use near....." part.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class DBTest{         public static void main(String[] args){                 try{                         Class.forName("com.mysql.jdbc.Driver").newInstance();                 } catch(Exception e){                         System.out.println(e);                         System.exit(0);                 }                 Connection conn = null;                 try {                         conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/testDB?" + "user=root&password=password");                         conn.close();                 } catch (SQLException ex) {                         // handle any errors                         System.out.println("SQLException: " + ex.getMessage());                         System.out.println("SQLState: " + ex.getSQLState());                         System.out.println("VendorError: " + ex.getErrorCode());                 }         } }
MySQL Server Version:
Server version: 5.0.67-0ubuntu6 (Ubuntu)

I've tried Drivers 5.1 , 5.0 and 3.1 now and I get the same problem every time. I've tried switching databases, users, etc but always get this same error:

I have the latest version of mysql from the Ubuntu repositories. Do I have to configure that a certain way? It isn't the URL which I supply that it does not like because I've tried multiple URLs and they all give me the same error when I supply the correct information.
Any help is greatly appreciated.This is.. very odd.
I have to ask are you really, really sure that your code is just as you posted? Are you sure you aren't running a query of some sort? My guess at this point would be some sort of rather bizarre encoding issue. I'm sorry but I can't reproduce your behaviour, I am connecting to different MySQL instances with no problem from Ubuntu..
Yes the code is exactly the same as what I posted (except hiding actual usernames and passwords)
I've even tried to connect to a remote mysql server and get the same behavior (If I type in the wrong database it alerts me there is no db of that name, if I lg in with the wrong password it alerts me cant login ____ @ ______, when I have all the correct information I get that same old error) , I'm somewhat convinced it's my driver now. I thought at first it was the way I had mysql configured but now I think it's my driver or the way I have everything installed. I simply put the driver location in the classpath and do the command:
export set CLASSPATH=/usr/share/tomcat5.5-webapps/ROOT/lib/mysql-connector-java-5.1.7-bin.jar
Was this the wrong way to go about doing it? I'm not currently running tomcat I simply put it there because a book said that's where it should go for tomcat, but I wanted to first try this not running tomcat with just a simple normal Java example.
