Can't use account manager with asmack

Hi

I am trying to use account manager with asmack but I am getting compiler error:

Here is my code:

    ConnectionConfiguration config = new ConnectionConfiguration("SERVER IP", 5222,"localhost");

    config.setSecurityMode(SecurityMode.disabled);

    XMPPConnection conn2 = new XMPPTCPConnection(config);

    conn2.connect();

    AccountManager am = new AccountManager(conn2);

In `AccountManager` line I am getting following error:

    The constructor AccountManager(XMPPConnection) is not visible

How can I resolve it ?
