The existing NullableType has been deprecated 5 years ago and causes crashes in Kotlin apps because Kotlin doesn't recognize this annotation as a nullable type annotation. While we can't align on a single @Nullable annotation yet, we can at least replace this one by JSR305's @Nonnull(MAYBE) as it fulfils all requirements, including full Kotlin compatiblity. To avoid the cumbersome name, we can redefine it as our own @NullableType annotation. (We can't use @Nullable to avoid name clashes with the main @Nullable annotation from AndroidX) Issue: google/ExoPlayer#6792 PiperOrigin-RevId: 540497469
