-------------------------------------------

Thanks Tim, Richard.
I'm sorry that I have not verified the fix in time, and if it's still needed(to close the bug), I confirm that everything was applied as expected.

Best regards,
   Nik.

> Hello,
> java.util.regex.MatchResult.group() throws unexpected IllegalStateException. According to the spec toMatchResult() 'Returns the match state of this matcher as a MatchResult. The result is unaffected by subsequent operations performed upon this matcher.' But, when invoking query methods on harmony MatchResult, IllegalStateException will be thrown out.
> The following test case will pass on RI, but fail on Harmony.
> public void test_toMatchResult() {
>         Pattern pattern = Pattern.compile("\\p{Lower}+");
>         Matcher matcher = pattern.matcher("test");
>         assertTrue(matcher.matches());
>         assertEquals("test", matcher.toMatchResult().group());
> }
> Best regards,
> Richard
