Oracle not providing osuser when there is a connection from a java program

I am trying to connect to my remote oracle database, and it is locked down and has a white list of users and pc's that they can connect from. However, oracle is not providing OSUSER when I attempt the connection so I'm getting denied.

Here is how I am connecting:

public static final String CONNECTION_STRING =  "jdbc:oracle:thin:@myip:port:db";
public static final java.util.Properties CONNECTION_PROPERTIES = new java.util.Properties();
static {
    CONNECTION_PROPERTIES.setProperty("password","password"); 
    CONNECTION_PROPERTIES.setProperty("user","dbuser"); 
    CONNECTION_PROPERTIES.put("v$session.osuser", System.getProperty("user.name").toString());
    try {
        CONNECTION_PROPERTIES.put("v$session.machine", InetAddress.getLocalHost().getCanonicalHostName());
    } catch (UnknownHostException e) {
        System.out.println("Failed to determine hostname. Attempting with Localhost, this is unlikely to succeed.");
        e.printStackTrace();

        CONNECTION_PROPERTIES.put("v$session.machine", "localhost");
    } 
    CONNECTION_PROPERTIES.put("v$session.program", "GDS_Reports"); 
}

and I make a connection like this:

  DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
  Connection conn = DriverManager.getConnection(GlobalConstants.CONNECTION_STRING, GlobalConstants.CONNECTION_PROPERTIES);

But the table reports these connections:

Some Oracle JDBC drivers have a bug so that OSUSER is not set see the fixed bugs in 10.2.0.4 so you need to upgrade to a newer version to fix that.

Oracle doesn't provide the osuser - it has to be told it by the client. You can code it into the java program. Details here.

Obviously, because you can do this, it is a pretty pointless security measure to whitelist on it.
