Why stream.collect(toList()) returns Object?

Question

How, technically speaking, collect(toList()) can return Object?

Stream y = Stream.of("X");
Object l = y.collect(Collectors.toList());

I would not be surprised by List, but Object that surprising.

Using the raw type `Stream` is the same as using its erasure, i.e. no generics at all. — Radiodef, Sep 15 '18 at 22:20

It can return List<String> also, but it is normal to get an Object because List is extended from Object.

final List<String> x = Stream.of("X").collect(Collectors.toList());
