[bug] javax.mail.internet.MimeUtility.getEncoding() never returns 'quoted-printable'

javax.mail.internet.MimeUtility.getEncoding() returns either "7bit" or =
"base64", but never "quoted-printable"

To reproduce:

####################################
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.nio.charset.Charset;

import javax.activation.DataSource;
import javax.mail.internet.MimeUtility;

public class Main {

	public static void main(String[] args) throws Exception {
	=09
		final Charset c =3D Charset.forName("ISO-8859-15");
		final byte[] b =3D "aaaa=E4".getBytes(c);
	=09
		System.out.println(MimeUtility.getEncoding(
				new DataSource(){

					public String getContentType() {
						return "text/plain; charset=3D"+MimeUtility.mimeCharset(c.name());
					}

					public InputStream getInputStream() throws IOException {
						return new ByteArrayInputStream(b);
					}

					public String getName() {
						return null;
					}

					public OutputStream getOutputStream() throws IOException {
						return null;
					}
				}
		));
	}
