So I checked in a patch for HARMONY-688's regex fix, and it passed the
regex unit tests, but causes the existing luni tests to fail in
java.util.Scanner. I've not figured out the base cause of the failure
so I've backed out the changes.

Hi regular expression guys:
After applying Harmony-688 on my local env. The following test case
will fail on Harmony but pass on RI
public void test_misc() {
String pattern = "*(\\p{javaDigit})++*";
I need to clarify here: the pattern is (\\p{javaDigit})++ ,but not
*(\\p{javaDigit})++*. I change the pattern into bold style, but when
sent out, they become two asterisks.
Matcher mat = Pattern.compile(pattern).matcher("123");
assertTrue(mat.matches());
}
Since in Scanner implementation, the pattern "(\\p{javaDigit})++" is
heavily utilized to recognize integer numbers, then many of Scanner
tests fail.
Greedy quantifiler here works fine.
But Greedy quantifiler is semantically insufficient, do need to use
double plus signs.
Would any regular expression guru look at this issue?
Best regards
