No suggestions in Code Ready Studio 12.16

I have tested the following code as per request from customer:

I tested the following: import java.util.ArrayList; import java.util.List; public class TestList

{ List<Integer> i=new ArrayList<>(); public static void main(String args[]) { i. }

}

I can see that there are no suggestions after "."

I did observer the same behavior on Eclipse Oxygen too

Is this expected behavior?

Customers started getting incorrect suggestions after upgrading code ready studio
Can someone please confirm.
