clarification for dstLength when chunked encoding

    /**

     * Copy the received data in a buffer. Data are handled as a stream, and are received upon applet request.

     * It is not possible to move backward in the data by using the <code>srcOffset>/code> parameter.

     * This is a non-blocking methid.

     * This is a non-blocking method.

     *

     * @param srcOffset the offset of the first byte to copy in the received data

     * @param dstBuffer a reference to the destination buffer

     * @param dstOffset the position in the destination buffer

     * @param dstLength the data length to be copied

     * @param dstLength the maximum number of bytes to be copied into dstBuffer, 

     * If fewer bytes are currently available (e.g. in the case of chunked transfer encoding),

     * the method will copy only the bytes available and return the actual number of bytes copied.

     * @return <code>dstOffset+length of the copied value</code>

     *

     * @exception  NullPointerException if <code>dstBuffer</code> is <code>null</code>
