Hi All!

It's incorrect.

He will have finished it.... This is the future perfect tense. The future perfect expresses an activity that will be completed before another time or event in the future.

He will have finished it by the time it's needed. OK
He will have finished it before six o'clock this evening. OK

It may be incorrect in American English, but this usage is fine in British English. We use the future perfect for assumptions about actions completed at the time of speaking. It may look strange to American speakers, but it's perfectly acceptable to Brits.;-)

If he's forty, he'll have graduated nearly twenty years ago.

Mick Jagger had dithered about when to get his knighthood from the Queen. All being well, he will have done it yesterday, but only after a savage attack on him by his musical partner, Keith Richards, for joining the Establishment and betraying the image of delinquency cultivated by the Rolling Stones.

Not common in American English apparently. The Spanish also have the same construction.
