title: QuickFIXJ FieldnotFound exception
body: <p>In my application I am receiving a huge FIX messages. Should I check the tag is present for all the tags I retrieving. If I am not checking the presence of a tag, I get FieldNotFound exception in case the tag is not exist in the message. Is there way to bypass the isSetField(Field) method for checking for the tag is present in the message. Any help would be appreciated.
  Thanks,
  Bibin</p>
