docs: {@link Collections#binarySearch(List, Object, Comparator) Searches} {@code sortedList} for
  {@code key} using the binary search algorithm. The list must be sorted using this ordering.
  
  @param sortedList the list to be searched
  @param key the key to be searched for
  @deprecated Use {@link Collections#binarySearch(List, Object, Comparator)} directly.
