> CharArrayReader.reset() behavior differs on Harmony and RI if the stream hasn't been marked
> If the stream was constructed to begin reading at a nonzero offset, Harmony reset the stream to the very beginning while RI reset it to the initial offset.
> Please, consider the following code:
> import java.io.CharArrayReader;
> import java.io.IOException;
> public class CharReaderTest {
> 	static String str = "offsetHello world!";
> 	static char[] data = new char[str.length()];
> 	static int offsetLength = 6;
> 	static int length = data.length - offsetLength;
> 	
> 	public static void main(String[] args) throws IOException {
> 		for(int i=0; i<str.length(); i++) data[i] = str.charAt(i);
> 		CharArrayReader reader = new CharArrayReader(data, offsetLength, length);
> 		System.out.print("Before reset(): ");
> 		for (int i = 0; i < length; i++) System.out.print((char) reader.read());
> 		reader.reset();
> 		System.out.print("\nAfter reset(): ");
> 		for (int i = 0; i < length; i++) System.out.print((char) reader.read());	
> 	}
> }
