SimpleDateFormat fails while parsing dates

Question

i have to parse a string representing a date, i did this test case which fails:
public void testParseDate4() throws Exception {
          dateAsString = "Fri, 01-Jan-2000 01:00:00 GMT+1";
          String datePattern = "EEE, dd-MMM-yyyy HH:mm:ss z";
          boolean correctlyParsed=false;
          try {
               SimpleDateFormat sdf = new SimpleDateFormat(datePattern);
               java.util.Date utilData = sdf.parse(dateAsString);
          }catch(Exception e) {
               e.printStackTrace();
               correctlyParsed=false;
          assertTrue("Assert date correctly parsed", correctlyParsed);
     }any help is very appreciated.

i must correct my self. i checked jdk 1.5 sources, and i found the code implementing that case:
case 17: // 'z' - ZONE_OFFSET
            int zoneIndex =
                formatData.getZoneIndex(calendar.getTimeZone().getID());
            if (zoneIndex == -1) {
                value = calendar.get(Calendar.ZONE_OFFSET) +
                    calendar.get(Calendar.DST_OFFSET);
          buffer.append(ZoneInfoFile.toCustomID(value));
            } else {
          int index = (calendar.get(Calendar.DST_OFFSET) == 0) ? 1: 3;
                if (count < 4) {
              // Use the short name
              index++;
          buffer.append(formatData.zoneStrings[zoneIndex][index]);
            break;i must be doing something unproper...
