I've seen this happen on multiple sites with various species of plants. Often an unusually hot and/or dry summer will trigger it, or else severe insect damage. Especially if the plant is partially or completely defoliated by the stress of it. Then, when more moderate conditions return, the tree "thinks" it's spring and blooms! I wouldn't worry about it too much, especially if the plant is established and has been there at least a few years. I would pinch off any fruit that tries to form, since it will be spoiled by freezing anyway.
