Draft JEP: Primitive Types in Patterns, instanceof, and switch (Second Preview)

[Stephan Herrmann]

The other day I stumbled upon this in the JLS changes for the first preview (JEP 
455):

* a widening reference conversion followed by an unboxing conversion
* a widening reference conversion followed by an unboxing conversion, then 
followed by a widening primitive conversion

I fail to imagine any type that can be widened to a boxing type. What's going on 
here?

best,
Stephan
