[ http://issues.apache.org/jira/browse/HARMONY-67?page=all ] Tim Ellison reopened HARMONY-67: --------------------------------
> java.nio.charset.Charset.decode(ByteBuffer) throws unexpected > BufferOverflowException for UTF-16BE, UTF-16LE, UTF-16 charsets. > ------------------------------------------------------------------------------------------------------------------------------- > > Key: HARMONY-67 > URL: http://issues.apache.org/jira/browse/HARMONY-67 > Project: Harmony > Type: Bug > Components: Classlib > Reporter: Svetlana Samoilenko > Assignee: Tim Ellison > > According to j2se 1.4.2 specification for Charset.decode(ByteBuffer b) the > method must not throw any exceptions. > The test listed below shows that there is unexpected BufferOverflowException > thrown if charset name is one in the following: UTF-16BE, UTF-16LE, UTF-16. > BEA does not throw any exceptions. > Code to reproduce: > import java.nio.charset.Charset; > import java.nio.ByteBuffer; > import java.nio.CharBuffer; > public class test2 { > public static void main(String[] args) throws Exception { > byte[] b = new byte[] {(byte)1}; > ByteBuffer buf= ByteBuffer.wrap(b); > CharBuffer charbuf=Charset.forName("UTF-16").decode(buf); > System.out.println("CharBuffer.length()="+ charbuf.length()); > } > } > 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.
