commit 4bfb469f82268c546688353cb08fea8d5c94f15f
Author: Yasser Zamani <ya...@apache.org>
AuthorDate: Mon Jul 13 20:14:17 2020 +0430

    fix unchecked generic for varargs compiler warning (#3997)
    
    * fix unchecked generic for varargs compiler warning
    
    to get rid of "unchecked generics array creation for varargs parameter" compiler warning
    
    * make SafeVarargs annotated method final
    
    By requiring that the method is final, the developer can guarantee that the declaration he made (namely that its varargs use is safe) is actually always true (provided of course that the developer actually provided a safe varargs method), and that it wasn't actually broken by a subclass incorrectly re-implementing the method.
