Tim Ellison commented on HARMONY-101: ------------------------------------- Svetlana, Until the HARMONY-39 contribution is accepted you won't have much joy with the regex code, since there are only compile-against stubs in the regex module. > NPE in java.util.regex.Pattern.compile() > ---------------------------------------- > > Key: HARMONY-101 > URL: http://issues.apache.org/jira/browse/HARMONY-101 > Project: Harmony > Type: Bug > Components: Classlib > Reporter: Svetlana Samoilenko > > According to 1.4.2 and 1.5 specifications for > java.util.regex.Pattern.matches(String regex,CharSequence input) > > An invocation of this convenience method of the form > Pattern.matches(regex, input); > behaves in exactly the same way as the expression > Pattern.compile(regex).matcher(input).matches() > Harmony throws unspecified NPE for Pattern.compile and returns false instead > of true for Pattern.matches(). > Code to reproduce: > import java.util.regex.Pattern; > public class test2 { > public static void main(String[] args) { > System.out.println("boolean is > true="+Pattern.matches("[,&&\\p{Punct}]", ",")); > System.out.println("boolean is > true="+Pattern.compile("[,&&\\p{Punct}]").matcher(",").matches()); > } > } > Steps to Reproduce: > 1. Build Harmony (check-out on 2006-01-30) j2se subset as described in > README.txt. > 2. Compile test2.java using BEA 1.4 javac > > javac -d . test2.java > 3.
