  The java.util.Locale.getISO3Language() works wrong for some codes which are
not ISO-639 language codes. It returns String result instead of throwing
MissingResourceException according to the specs: "Throws
MissingResourceException if the three-letter language abbreviation is not
available for this locale".

Here is a test demonstrating the bug.
---------------ISO3LanguageTest.java----------
import java.util.Locale;
import java.util.MissingResourceException;

public class ISO3LanguageTest {
  public static void main(String args[]) {
    Locale locale = new Locale("ttt", "");

    try {
      String result = locale.getISO3Language();

      System.out.println(
        "Failed: getISO3Language() returns wrong result : " + result + "\n" +
        "for locale \"" + locale + "\""
      );
    } catch(MissingResourceException e) {
      System.out.println("Passed");
    }
  }
}
----------The test example---------
> java ISO3LanguageTest
Failed: getISO3Language() returns wrong result : tat
for locale "ttt"
