Vladimir Strigun commented on HARMONY-33:
-----------------------------------------
Hi Paulex,
I can't reproduce IllegalStateException with my fix and with next test:
import java.nio.*;
import java.nio.charset.*;
public class Harmony33 {
public static void main(String[] args) {
try{
ByteBuffer bb = ByteBuffer.allocate(1);
bb.put(0,(byte)77);
CharsetDecoder utf16D = Charset.forName("UTF-16").newDecoder();
CharBuffer cb =
utf16D.onMalformedInput(CodingErrorAction.REPLACE).onUnmappableCharacter(CodingErrorAction.REPLACE).decode(bb);
}catch(Exception e){
e.printStackTrace();
}
}
}
Possibly, you used not complete fix. My initial fix remove line "continue;"
after checking remaining value of CharBuffer. But if I don't remove "continue;"
line after the check I get same exception:
java.lang.IllegalStateException
at java.nio.charset.CharsetDecoder.flush(Unknown Source)
at java.nio.charset.CharsetDecoder.decode(Unknown Source)
at Harmony33.main(Harmony33.java:11)
> java.nio.BufferOverflow exception while decoding ByteBuffer with UTF-16
