Note this is generally not safe: it introduces data race on langReflectAccess field access. It has
to be proved that everything that implements LangReflectAccess interface makes this data race
benign: e.g. all fields that are accessed via those implementation are final, read once, etc. And
briefly looking at that, I am not sure it is the case for the actual accessor generators.
I'd cautiously leave "volatile" here.
