Review Comment:
> I suspect this flag is excessive ... From what I see the method either
checks/creates necessary directory or throws an exception if something goes
wrong.
In case all directories from `cft.storages()` was created in
`checkAndInitCacheWorkDir` method will return `false`.
If some directory was created earlier then method will return `true`.
So, it seems to me flag required.
