There is `testImmutableCollection`/`testImmutableSet` that takes an arbitrary
nonexistent item for insertion/removal:
https://github.com/openjdk/jdk/blob/598af2e51464be089b64da4024e62865c2c6ec72/test/jdk/java/util/Collection/MOAT.java#L665
I think a refactor of a generic `testCollMutatorsAlwaysThrow(Collection<T> c, T
t)` and delegating the original Integer version to call
`testCollMutatorsAlwaysThrow(c, ABSENT_VALUE)` would not be invasive.
