After upgrading my project to 4.2 my tests failed with a message that
$key
variable is missing here:symfony/src/Symfony/Component/Cache/Traits/ArrayTrait.php
Line 131 in e812852
So I added that variable to the trait and method calls (are there any other?). This is internal class so I guess noone is using it anywhere.
Anyway, my tests pass with this fix.
