public class NPETest {

    public static void main(String[] args) {
        DataFlavor flavor1 = new DataFlavor("text/plain; charset=unicode; class=java.io.InputStream", "Flavor 1"); 
        DataFlavor flavor2 = new DataFlavor("text/plain; class=java.io.InputStream", "Flavor 2"); 
        DataFlavor[] flavors = new DataFlavor[] { flavor1, flavor2 };
        DataFlavor best = DataFlavor.selectBestTextFlavor(flavors);
        System.out.println("best=" + best);
    }
}

EVALUATION The problem is that on Win32 ISO8859_1 was returned as default charset. This value is already alias name and so CharacterEncoding.aliasName(...) for this value returns null. The fix is as follows: if CharacterEncoding.aliasName(...) returns null for some value, we should assume that the value is already alias name and use it as such. ###@###.### 2000-09-18
