Java regex is working in my system but not in the server

The regular expression is

String regex = "^[\\p{IsHangul}\\p{IsDigit}]+";

And whenever i do

text.matches(regex);

It works fine in my system but not in some of the system. I am not able to track the issue.

Thank you in advance.

Exception:

Exception in thread "main" java.util.regex.PatternSyntaxException: Unknown character property name {Hangul} near index 13
^[\p{IsHangul}\p{IsDigit}]+
             ^

It seems that Java version you are using is not able to recognise Hangul as correct script character so you can try to create your own character class which will cover same range as Hongul from newer versions of Java.

From what I see in code in source code of Character.UnicodeScript on Java 8 Hangul refers to Unicode ranges

  • 1100..11FF
  • 302E..302F
  • 3131..318F
  • 3200..321F
  • 3260..327E
  • A960..A97F
  • AC00..D7FB
  • FFA0..FFDF

so maybe try with such pattern

Pattern.compile("^["
        + "\u1100-\u11FF"
        + "\u302E-\u302F"
        + "\u3131-\u318F"
        + "\u3200-\u321F"
        + "\u3260-\u327E"
        + "\uA960-\uA97F"
        + "\uAC00-\uD7FB"
        + "\uFFA0-\uFFDF"
        + "\\p{IsDigit}]+");

According to Using Regular Expressions in Java:

Java 5 fixes some bugs and adds support for Unicode blocks. ...

Make sure you're using Java 5+ in the server.
