[ http://issues.apache.org/jira/browse/HARMONY-99?page=all ] Tim Ellison closed HARMONY-99: ------------------------------
Verified by Svetlana > java.nio.charset.CharsetDecoder.decode(ByteBuffer in) does not throw > MalformedInputException when buffer's current position is not legal > ---------------------------------------------------------------------------------------------------------------------------------------- > > Key: HARMONY-99 > URL: http://issues.apache.org/jira/browse/HARMONY-99 > Project: Harmony > Type: Bug > Components: Classlib > Reporter: Svetlana Samoilenko > Assignee: Tim Ellison > Attachments: CharsetDecoder_patch.txt > > According to 1.4.2 and 1.5 java.nio.charset.CharsetDecoder.decode(ByteBuffer > in) throws > MalformedInputException - If the byte sequence starting at the input buffer's > current position is not legal for this charset and the current > malformed-input action is CodingErrorAction.REPORT. > Harmony does not throw MalformedInputException in this case as test listed > below shows. > Code to reproduce: > import java.nio.*; > import java.nio.charset.*; > public class test2 { > public static void main(String[] args) throws Exception { > Charset cs =Charset.forName("utf-16"); > CharsetDecoder decoder = cs.newDecoder(); > decoder.onMalformedInput(CodingErrorAction.REPORT); > decoder.onUnmappableCharacter(CodingErrorAction.REPORT); > > CharBuffer out = CharBuffer.allocate(10); > ByteBuffer in = ByteBuffer.wrap(new byte[] { 109, 97, 109}); > CharBuffer res1 = decoder.decode(in); > //output > System.out.println("CharBuffer=="+res1); > System.out.println("CharBuffer.position =="+res1.position()); > > System.out.println("toHexString=="+Integer.toHexString(res1.charAt(0))); > System.out.println("ByteBuffer.position()=="+in.position()); > System.out.println("ByteBuffer.remaining()=="+in.remaining()); > } > } > 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.
