About Question enthuware.ocpjp.ii.v11.2.3358 :

[mdraisma]

Maybe an extra explanation is in order for the fact that try(d1; ...) is a thing now (the object itself is created before the try statement).

[admin]

Explanation has been enhanced to explain that it is ok to put d1 in try-with-resources block because it is effectively final.
thank you for your feedback!

I did not notice d1 hidden in the corner!
