I mean the issue was thrown before the review, that may be considered it
was not a principal problem, deprecating `Class.newInstance` most reason is
used to fix undeclared checked exceptions (even if there is a little
performance cost). And I think JDK's API developer should not make hasty
decision. Maybe we can watch the JDK's implementation about both of them with
IDE.

> Priority: Minor
>
> Class#newInstance is deprecated starting in Java 9 -
> https://bugs.openjdk.java.net/browse/JDK-6850612 - because it may throw
> undeclared checked exceptions.
> The suggested replacement is getDeclaredConstructor().newInstance(), which
> wraps the checked exceptions in InvocationException.
