Review comment:
It's okay to throw NPE here if there is a bug and we accidentally pass
`null` into this method. Actually `Preconditions.checkNotNull()` also throws
NPE. Here we just remove the extra check because this method could be called
frequently. Added an assert to cache the `null` value in the test
