I have a reproducible test case:

public class TestCase {

    private final java.util.function.Consumer emptyCallback = result -> {};

    p

    You can find an official bug report here. The issue is fixed in Java 9.
    


    


    You can return inside a constructor
    


    
  
    A return statement returns control to the invoker of a method (§8.4,
  §15.12) or constructor (§8.8, §15.9).
