Check to see if DateTime will be an older version of JodaTime in the future

Question

I have a unique situation. I'm working on an old project that resides on an old WebLogic server that (A) doesn’t skip anything from Java 6 and (B) pollutes the class loader with the old version of JodaTime (version 1.2, to be precise).

The client I'm working on has a standard development platform that includes Java 8 and JodaTime for projects that are stuck in earlier versions of Java. So I got stuck using this old version of JodaTime (310-Backport would be a great solution, but I am not allowed to use it).

I need to create a utility method that checks if DateTimeafter today (regardless of time). JodaTime 1.2 doesn’t have LocalDateany convenient static factory methods like now(), so I came up with the following:

public static boolean isAfterToday(DateTime dateTime) {
  YearMonthDay date = new YearMonthDay(dateTime);
  YearMonthDay today = new YearMonthDay();
  return date.isAfter(today);
}

This is a bit unpleasant, because in later versions of JodaTime everything in the class YearMonthDayis deprecated and replaced with LocalDate, which, unfortunately, I can not use. Is there a better way to do this? Also, I am trying to take the time off DateTimeby converting it to YearMonthDay... are there any "gotchas" that I skip or should know?

, GMT, :

public static boolean isAfterToday(DateTime dateTime) {
    String dateTimeStr = dateTime.toString("yyyy-MM-dd");
    String nowStr = new DateTime().toString("yyyy-MM-dd");
    return dateTimeStr.compareTo(nowStr) > 0;
}

:

private static final DateTimeFormat yearMonthDay = DateTimeFormat.forPattern("yyyy-MM-dd");

public static boolean isAfterToday(DateTime dateTime) {
    String dateTimeStr = yearMonthDay.print(dateTime);
    String nowStr = yearMonthDay.print(new DateTime());
    return dateTimeStr.compareTo(nowStr) > 0;
}
