There is a bug in stub code of AArch64 String.compareTo() intrinsics. It can be reproduced by below Java code and VM options.
public class Test {
public static void main(String[] args) {
String str1 = "/home/pengfei/backup/Android/projects/ActionBarSherlock/tree/master/actionbarsherlock/res/";
String str2 = "/home/pengfei/backup/Android/projects/ActionBarSherlock/tree/master/actionbarsherlock/res/\u6d4b\u8bd5.png";
System.out.println(str1.compareTo(str2));
}
}
// $ java -Xint Test
// -6
