              Description

              Soft, weak, and phantom references are automatically-cleared references (see JDK-8071507). The referent is cleared before the reference object is enqueued.

              The `enqueue` method should behave the same and it should clear the reference before enqueuing it to the registered queue.

              Surveying the existing usage of this enqueue method, it's a common pattern that Reference::clear is called before or after enqueuing.
