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

the regular expression is

string regex = "^[\\p{ishangul}\\p{isdigit}]+"; 

and whenever do

text.matches(regex); 

it works fine in system not in of system. not able track issue.

thank in advance.

exception:

exception in thread "main" java.util.regex.patternsyntaxexception: unknown character property name {hangul} near index 13 ^[\p{ishangul}\p{isdigit}]+              ^        @ java.util.regex.pattern.error(pattern.java:1713)        @ java.util.regex.pattern.charpropertynodefor(pattern.java:2437)        @ java.util.regex.pattern.family(pattern.java:2412)        @ java.util.regex.pattern.range(pattern.java:2335)        @ java.util.regex.pattern.clazz(pattern.java:2268)        @ java.util.regex.pattern.sequence(pattern.java:1818)        @ java.util.regex.pattern.expr(pattern.java:1752)        @ java.util.regex.pattern.compile(pattern.java:1460)        @ java.util.regex.pattern.<init>(pattern.java:1133)        @ java.util.regex.pattern.compile(pattern.java:823)        @ java.util.regex.pattern.matches(pattern.java:928)        @ java.lang.string.matches(string.java:2090)        @ com.mycompany.helper.applicationhelper.main(applicationhelper.java:200) 

it seems java version using not able recognise hangul correct script character can try create own character class cover same range hongul newer versions of java.

from see in code in source code of character.unicodescript on java 8 hangul refers unicode ranges

• 1100..11ff
• 302e..302f
• 3131..318f
• 3200..321f
• 3260..327e
• a960..a97f
• ac00..d7fb
• ffa0..ffdf

so maybe try such pattern

pattern.compile("^["         + "\u1100-\u11ff"         + "\u302e-\u302f"         + "\u3131-\u318f"         + "\u3200-\u321f"         + "\u3260-\u327e"         + "\ua960-\ua97f"         + "\uac00-\ud7fb"         + "\uffa0-\uffdf"         + "\\p{isdigit}]+");
