Review comment:
I think this should be something else than `null` - did the old
behaviour accept `null` as a valid path? I believe `Files.isDirectory(null)`
returned false....
looking from the other end: I don't think `null` should be accepted as a
"writeabledirectory"

this change will leave the file registered in the shutdownmanager in
case the file was already deleted

Review comment:
I think at some point we should probably introduce some rule to ensure
that every file ends with a newline...but for now: could you add one here ? :D

Review comment:
I know it's probably out of scope in this patch - but in case the value
is already "interned" - then it will not change; at a cost of a conditional we
can skip the hash lookup(put) as well
