 /**
  * InternetHeaders is a utility class that manages RFC822 style
  * headers. Given an RFC822 format message stream, it reads lines
  * until the blank line that indicates end of header. The input stream
  * is positioned at the start of the body. The lines are stored
  * within the object and can be extracted as either Strings or
  * {@link Header} objects. <p>
  * <p/>
  * This class is mostly intended for service providers. MimeMessage
  * and MimeBody use this class for holding their headers. <p>
  * <p/>
  * <hr> <strong>A note on RFC822 and MIME headers</strong><p>
  * <p/>
  * RFC822 and MIME header fields <strong>must</strong> contain only
  * US-ASCII characters. If a header contains non US-ASCII characters,
  * it must be encoded as per the rules in RFC 2047. The MimeUtility
  * class provided in this package can be used to to achieve this.
  * Callers of the <code>setHeader</code>, <code>addHeader</code>, and
  * <code>addHeaderLine</code> methods are responsible for enforcing
  * the MIME requirements for the specified headers.  In addition, these
  * header fields must be folded (wrapped) before being sent if they
  * exceed the line length limitation for the transport (1000 bytes for
  * SMTP).  Received headers may have been folded.  The application is
  * responsible for folding and unfolding headers as appropriate. <p>
