It seems too eager when @NonNullByDefault(TYPE_ARGUMENT) leads to the assumption that   map.get(someValue) will always return a non-null value.

My code:

private Map<String, BundleFrequency> bundles = Maps.newTreeMap();


@Nullable BundleFrequency frequency = bundles.get(key(bundle)); // this can be null (frequency == null) { // here the compiler complains frequency cannot be null
 frequency = new BundleFrequency(bundle.getName(), bundle.getVersion(), 0);
 bundles.put(key(bundle), frequency);
}

The same will likely happen for list.get(index) and other methods.
