             Summary: Avoid calling Class#newInstance
                 Key: FLINK-8933
                 URL: https://issues.apache.org/jira/browse/FLINK-8933
             Project: Flink
          Issue Type: Task
            Reporter: Ted Yu

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.
