I think you don't need to do cached!! in else part. just cached should be fine.

@Rajkumar Singh Would be true if it was a local variable, but it's a member variable.

BTW, I think it'd be safer to use lazy { } for cached.

Definitely, especially since it'll prevent the race condition you currently have.
