public @interface NotThreadSafe
The presence of this annotation indicates that the author believes the class is not thread-safe.
The absence of this annotation does not indicate that the class is thread-safe, instead this annotation is for
cases where a naïve assumption could be easily made that the class is thread-safe. In general, it is a bad plan
to assume a class is thread safe without good reason.
