Review comment:
@vvysotskyi I already explained reasons to keep `Preconditions` in my other
comments. Here is the summary in random order:
- The change does not remove the dependency on the guava library.
- `Preconditions` are not deprecated by the guava team and provides a stable
interface.
- `Preconditions` functionality is much wider compared to JDK classes.
- Using `Preconditions` will be more consistent with other checks like
`checkState` or `checkArgument` and also with other Apache projects.
- It avoids unnecessary changes and keeps original contributions.
