hmm, according to the
[javadocs](https://docs.oracle.com/javase/7/docs/api/java/lang/reflect/InvocationTargetException.html)
the wrapped exception is part of the exception chain and accessible via
`getCause()`. Can't try it out mself at the moment though.
> Avoid calling Class#newInstance

> Project: Flink
> Issue Type: Task
> Reporter: Ted Yu
> Assignee: vinoyang
> 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.
