  !
  ! This file is divided into two parts:
  ! 1. APPROVED EXCLUSIONS
  ! 2. TEMPORARY (UNAPPROVED) EXCLUSIONS
  !
  ! Approved exclusions come in two sub-types:
  ! 1. general exclusion of a named bug pattern, meaning that all instances that matches the bug
  !    pattern identifier are excluded;
  ! 2. specific exclusions for a named bug pattern, meaning that all instance exclusions are
  !    explicitly enumerated;
  !
  ! All specific exclusions must be accompanied inline (i.e., in the affected source code) by
  ! a commented out annotation of the form:
  !
  ! // @SuppressFBWarnings("pattern identifier")
  !
  ! where pattern identifier is one of findbugs' named patterns. At an appropriate point in the
  ! future, these commented out annotations will be uncommented and exclusion patterns removed
  ! from this file.
  !
  ! Temporary (unapproved) exclusions are short-term work arounds that should be removed as
  ! soon as possible by either (1) fixing (eliminating) cause of warning, or (2) conversion to
  ! approved exclusion.
  !
  ! The organization of pattern matches employs the following levels (from top down):
  ! 1. bug pattern
  ! 2. or clause matching instances
  ! 3. class name, if applies to class/interface
  ! 4. and clause matching class/instance and single or or clause of multiple {method,field} members
  !
  ! for example,
  !
  ! <Match>
  !   <Bug pattern="pattern identifier"/>
  !   <Or>
  !     <And>
  !       <Class name="dotted class name"/>
  !       <Member name="unqualified member name"/>
  !     </And>
  !   </Or>
  ! </Match>
