The combination of CASE_INSENSITIVE | UNICODE_CASE causes an incorrect match.

======= Test Code ========

import java.util.regex.*;

public class Test
{
        public static void main(String args[])
        {
                 Pattern p1 = Pattern.compile("aa",(Pattern.CASE_INSENSITIVE) | (Pattern.UNICODE_CASE));
                 Matcher m1 = p1.matcher("ab");
                 System.out.println("Pattern=\"aa\" CASE_INSENSITIVE | UNICODE_CASE; String=\"ab\" => match="+m1.matches());

                 Pattern p2 = Pattern.compile("aa",Pattern.CASE_INSENSITIVE);
                 Matcher m2 = p2.matcher("ab");
                 System.out.println("Pattern=\"aa\" CASE_INSENSITIVE; String=\"ab\" => match="+m2.matches());

                 Pattern p3 = Pattern.compile("aa",Pattern.UNICODE_CASE);
                 Matcher m3 = p3.matcher("ab");
                 System.out.println("Pattern=\"aa\" CASE_INSENSITIVE; String=\"ab\" => match="+m3.matches());

                 Pattern p4 = Pattern.compile("aa",(Pattern.UNICODE_CASE | Pattern.DOTALL));
                 Matcher m4 = p4.matcher("ab");
                 System.out.println("Pattern=\"aa\" CASE_INSENSITIVE | DOTALL; String=\"ab\" => match="+m4.matches());
