Re: [classlib][regex] Is this a issue of java.util.regex.Matcher.region(int, int);
Hello Spark Shen, It seems that Matcher.region(int, int) will not have any effects when called. This can be demonstrated by the following test case there is an issue quite similar to one you have raised filled by Richard: http://issues.apache.org/jira/browse/HARMONY-759 I'll try to provide a fix today, thanks for reminding. BTW, there are other issues about java.util.regex. If necessary, can we disscuss all these issues case by case. Surely, we can discuss issues if needed, but if smth just does not work, please fill an issue in JIRA, I'm looking after regex issues. If you need some problems to fix urgently, let me know separately.

If you need some problems to fix urgently, let me know separately. Thank you very much, do I need to raise a new JIRA for this issue? Using the test case I give, I debug into the code. The calling stack is as follow: SequenceSet.indexOf(CharSequence, int) SequenceSet.find(int, CharSequence, MatchResultImpl) line: 69 SingleSet.find(int, CharSequence, MatchResultImpl) line: 52 Matcher.findAt(int) line: 317 Matcher.find(int) line: 304 Matcher.find() line: 342 in indexOf line 115 : int last = string.charAt(charCount - 1); the value of string is c. I figure out this string variable is a member of SequenceSet. Since the region in my test case setting is (0, 2), I am not sure whether the string value here should be smth like a. Since SequenceSet is construct when Pattern.complile() and this members value of the constructed SequenceSet seems never change ever since, does it make sense that when region is called, value of SequeceSet should also be updated? Hope this guess would be helpful. :-) Correct me if I am wrong.

[classlib][regex] Is this a issue of java.util.regex.Matcher.region(int, int);
Hi All: It seems that Matcher.region(int, int) will not have any effects when called. This can be demonstrated by the following test case: public void test_RegionII() { CharBuffer buffer = CharBuffer.wrap(new char[] { 'a', 'a', 'b', 'b', '.', 'c' }); Matcher matcher = Pattern.compile(c).matcher(buffer); //$NON-NLS-1$ matcher.region(0, 2); assertFalse(matcher.find()); } This test case pass on RI, but fail on Harmony. Can I infer that, harmony ignores region settting when trying to find the specified pattern? Correct me if I am wrong.
