Commit
This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
While the `@NotNull` decorator informs developers that the correct usage is that the decorated variables should not be `null`, it does not enforce such in any way. This leads to cases where an incorrectly fed `null` could propagate far away before being detected (such as via `NullPointerException`s). This commit implements some `null` guards where needed for a fail-fast treatment of `null` inputs.
