  The java.util.TimeZone.getDisplayName(boolean, int) and getDisplayName(
boolean, int, Locale) works wrong if its second argument is not TimeZone.SHORT
and not TimeZone.LONG. It doesn't throw IllegalArgumentException.

Here is a test demonstrating the bug.
----------GetDisplayNameTest.java----------
import java.util.Locale;
import java.util.TimeZone;

public class GetDisplayNameTest {
  public static void main(String args[]) {
    try {
      TimeZone tz = TimeZone.getTimeZone("GMT");
      String name = tz.getDisplayName(true, Integer.MAX_VALUE,
                                        Locale.getDefault());

      System.out.println("Failed. IllegalArgumentException haven't been thrown");
    } catch(IllegalArgumentException e) {
      System.out.println("Passed");
    }
  }
}
----------The test output-------
<avv@stardust(pts/3).570> java -version
java version "1.2beta4"
Classic VM (build JDK-1.2beta4-J, green threads, sunwjit)
<avv@stardust(pts/3).571> java GetDisplayNameTest
Failed. IllegalArgumentException haven't been thrown
