> Assertion refers to the following scenario:
> {code}
> IgniteUuid oldId = meta.putIfAbsent(parentId, fileName, info);
> if (oldId == null)
>     break;
> if (!overwrite)
>     throw new IgfsPathAlreadyExistsException("Failed to create file (file already exists): " + path);
> IgfsFileInfo oldInfo = meta.info(oldId);
> assert oldInfo != null;
> {code}
> Old info is null for some reason. Need to investigate whether assertion is valid and who may remove it concurrently. 
> Can it be a cache consistency issue in client mode?
