   * $Log: AddressParser.java,v $
   * Revision 1.11  2009/10/22 10:26:27  jbemmel
   * Fix for issue #230, restructured the code such that parsing for any address appearing without '<' '>'

   * Revision 1.9  2007/02/12 15:19:26  belangery
   * Changed the encode() and encodeBody() methods of SIP headers and basic classes to make them use the same StringBuffer instance during the encoding phase.
   *
   * Revision 1.8  2007/02/06 16:40:02  belangery
   * Introduced simple code optimizations.
