Work Description: lgajowy commented on pull request #9613: [BEAM-3845] Remove deprecated Class.newInstance() method usage
URL: https://github.com/apache/beam/pull/9613
`Class.newInstance()` is deprecated since Java 9. See more verbose description on Jira.
I searched for all `Class.newInstance()` usages in Beam's codebase and It seems that this was the only one usage of `Class.newInstance()` in beam codebase left. :) Other places that require the new instance use either `Constructor.newInstance()` or `Class.getDeclaredConstructor().newInstance()`. Both replacements are acceptable and are not deprecated in Java 9.
@iemejia could you take a look?

> 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.
