How about caching the default bundle:

private static final ResourceBundle defaultBundle =
   ResourceBundle.getBundle(bundleName, Locale.getDefault());

private static synchronized Calendar
getInstance(TimeZone zone, Locale locale, ResourceBundle bundle)
{
   String calendarClassName = bundle.getString("calendarClass");
   if (calendarClassName != null)
     ...
}

public static Calendar getInstance()
{
   return getInstance(TimeZone.getDefault(), Locale.getDefault(),
     defaultBundle);
}

public static Calendar getInstance(TimeZone zone)
{
   return getInstance(zone, Locale.getDefault(), defaultBundle);
}
