[xSocket-develop] Fwd: i got an error with xSocket V1_2_1

[PyungMoon O. <qud...@gm...>]

i found it..

in the below source code..remainingToExtract  value was minus value..


public LinkedList<ByteBuffer> extract(LinkedList<ByteBuffer> inOutBuffer,
int length) throws IOException, BufferUnderflowException {

        LinkedList<ByteBuffer> result = new LinkedList<ByteBuffer>();

        int remainingToExtract = length;
        ByteBuffer buffer = null;

        do {
            // get the next buffer
            buffer = inOutBuffer.remove();
            if (buffer == null) {
                throw new BufferUnderflowException();
            }

            // can complete buffer be taken?
            int bufLength = buffer.limit() - buffer.position();
            if (remainingToExtract >= bufLength) {
                // write taken into out channel
                result.addLast(buffer);
                remainingToExtract -= bufLength;

            // .. no
            } else {
                int savedLimit = buffer.limit();

                // extract the takenable
                buffer.limit(buffer.position() + remainingToExtract);
                ByteBuffer leftPart = buffer.slice();
                result.addLast(leftPart);
                buffer.position(buffer.limit());
                buffer.limit(savedLimit);
                ByteBuffer rightPart = buffer.slice();
                inOutBuffer.addFirst(rightPart);
                break;
            }

        } while (remainingToExtract > 0);

        return result;
    }

i got an error message like this..
but i think it can not be happen if there is no another thread which is
accessing the buffer..
as i know "public LinkedList<ByteBuffer> extract(LinkedList<ByteBuffer>
inOutBuffer, int length) throws IOException, BufferUnderflowException {"
method check limit before call " java.nio.Buffer.limit" method..
am i right??

but i can not find it..

can someone tell me why it's happening?? and which threads are accessing the
buffer?
