Description: ###@###.###

The following test reproduces the problem:
--------------------------------------------------------
import java.awt.datatransfer.DataFlavor;

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);
    }
}
--------------------------------------------------------

The test case throws the following exception:
--------------------------------------------------------
Z:\bug\newbug>K:\das\merlin\build\win32\bin\java NPETest
Exception in thread "main" java.lang.NullPointerException
        at java.awt.datatransfer.DataFlavor.selectBestTextFlavor(DataFlavor.java:615)
        at NPETest.main(NPETest.java:9)
--------------------------------------------------------

This regression is introduced with the fix for 4275210.
