Hi Daniel,
unfortunately, your proposed solution does not work with javac. I get this in
the build:
Oh darn. I should have double checked.
Can we at least reduce the scope of the @SuppressedWarnings by
introducing a private method that just has the return call?

where U#1,U#2,T are type-variables:

U#2 extends Object declared in method <U#2>thenCompose(Function<? super T,? extends

1 error
So I think we need to go back to my initial proposal which works for both, IDE and javac:http://cr.openjdk.java.net/~clanger/webrevs/8223553.0/
Thanks
