Use yet more `assertThrows` (and a tiny bit more Truth).
Use more static imports.
Run `@LargeTest` tests under Android emulators by default.
Tweak some tests after the migration of https://github.com/google/guava/commit/6dc6797207ef8c1282cdcf09bec77ecf6e5b8c3e.
Add some more `@Nullable` annotations, mostly in null-unmarked code.
Internal change.
Use some collection constructors (and a few more static imports).
Adapt to the once and future TODO style.
Use `TestParameterInjector` in `NullPointerTesterTest`.
Rename the remaining `PackageSanityTests` (plural) classes to "`PackageSanityTest`" (singular).
Migrate parts of `javatests/com/google/common/testing/...` from JUnit3 to JUnit4, so that we can use `TestParameterInjector` in an upcoming CL.
Address some more counterfactual [CheckedExceptionNotThrown](https://errorprone.info/bugpattern/CheckedExceptionNotThrown) findings.
