    Details

    • Resolved In Build:
      beta

      sparc

      Description

      \Z should treat a \u0085 at the end of input like a \n unless
      unix lines is enabled.

      Also

      \G should really match where the last match occurred, not where
      the next match starts.

      test cases

      import java.util.regex.*;

      public class test1 {
        public static void main(String [] args) {
          Pattern p = Pattern.compile("foo\\Z");
          Matcher m = p.matcher("foo\u0085");
          if (m.matches())
            System.out.println("matches");
          else
            System.out.println("fails");
         }
      }

      should match.

      Also

      import java.util.regex.*;

      public class test {
        public static void main(String [] args) {
          System.out.println(Pattern.compile("\\GA*")
                                    .matcher("1A2AA3")
                                    .replaceAll("X"));
         }
      }

      should print "X1A2AA3".
