Tim Ellison reassigned HARMONY-98: ---------------------------------- Assign To: Tim Ellison > java.util.BitSet.clear(int toIndex,int fromIndex) throws unexpected > IndexOutOfBoundsException when toIndex=fromIndex > -------------------------------------------------------------------------------------------------------------------- > > Key: HARMONY-98 > URL: http://issues.apache.org/jira/browse/HARMONY-98 > Project: Harmony > Type: Bug > Components: Classlib > Reporter: Svetlana Samoilenko > Assignee: Tim Ellison > Attachments: fix.txt, fix_hrm-98.txt > > According to 1.4.2 and 1.5 specification java.util.BitSet.clear(int,int) > throws IndexOutOfBoundsException - if fromIndex is negative, or toIndex is > negative, or fromIndex is larger than toIndex. > Harmony throws IndexOutOfBoundsException if toIndex=fromIndex. > Code to reproduce: > import java.util.BitSet; > public class test2 { > public static void main(String[] args) { > BitSet set = new BitSet(); > for(int i=0; i < 20; i++) { > set.set(i); > } > set.clear(10,10); > } > } > 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.
