It refers to "the practice ... in ORO classes", but only Perl5Util throws a NullPointerException if toString() is called when there is no match. Perl5Util has to honor the MatchResult interface. Returning Object.toString() violate the MatchResult contract. However, it is undesirable to throw an exception when MatchResult requires group() to return null when there is no matched group and toString() returns group(0). Therefore, Perl5Util.toString() has been changed to return null if there is no match, which is the original intended behavior.
