[ http://issues.apache.org/jira/browse/LANG-291?page=all ]
David J. M. Karlsen updated LANG-291: ------------------------------------- Attachment: ObjectUtils-patch-rev470351.txt PLease delete the DateUtils patch, and use this more general patch with max(Comparable, Comparable) an min(Comparable, Comparable) methods in ObjectUtils. A compareTo( Comparable, Comparable ) is left out, as this would violate Java protocol, see http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Comparable.html "Note that null is not an instance of any class, and e.compareTo(null) should throw a NullPointerException even though e.equals(null) returns false." > Null-safe comparison methods for finding most recent / least recent dates. > -------------------------------------------------------------------------- > > Key: LANG-291 > URL: http://issues.apache.org/jira/browse/LANG-291 > Project: Commons Lang > Issue Type: Improvement > Environment: N/A > Reporter: David J.
