The methods
    public String getByteToCharEncodingForCharset(String charset)
    public String getCharToByteEncodingForCharset(String charset)
of class java.awt.datatransfer.TextFlavor
dont return getDefaultCharset() for null input parameter as doc says.

The JDK javadoc comment says:
--------------------------------------------------
    /**
     * Gets the encoding that can be used to interpret this
     * charset. For instance, <code>ISO8859_1</code> decoding
     * <i>may</i> be used to interpret an <code>ascii</code>
     * charset stream. The value returned can be passed in
     * as a character encoding to other JDK classes, such as
     * <code>java.io.InputStreamReader</code>.
     * <p>
     * The MIME specification requires that all MIME values
     * be lower case. MIME types with upper-case values are
     * in error and may yield unpredictable results.
     * </p>
     *
     * @param charset The charset to be decoded. If charset is
     * <code>null</code>, the value returned by
     * <code>getDefaultCharset()</code> is used.
                    ^^^^^^^^^^^^^^^^^^^
     *
     * @return the appropriate character encoding, or <code>null</code>
     * if no decoder is available.
     */

    public String getByteToCharEncodingForCharset(String charset)
    
    public String getCharToByteEncodingForCharset(String charset)

The test demonstrating the bug:
-----------------Test.java------------------------
mport java.awt.datatransfer.*;

public class Test {

    public static void main(String[] args) {
        try {
            TextFlavor tf = new TextFlavor("text/plain");
            System.out.println("getDefaultCharset(): "+tf.getDefaultCharset());

            System.out.println("getByteToCharEncodingForCharset(null): "+
                               tf.getByteToCharEncodingForCharset(null));
            System.out.println("getCharToByteEncodingForCharset(null): "+
                               tf.getCharToByteEncodingForCharset(null));

            System.out.println(tf.getCharToByteEncodingForCharset(null).equals(tf.getDefaultCharset()));
            
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
    }
}
