Yes, probably a little easier for field access (array access is more involved). However, in my experience the process of modifying the j.u.concurrently classes and replacing Unsafe with VarHandle was not that arduous and rather quick.

I suspect both would be easily amenable to some automatic transformation via an IDE [*].


[*] And maybe byte code transformations, which would be rather handy for testing with say jcstress tests.
