Doesn't say anything about the name. Trademark law and copyright law are related but very distinct. If Oracle owns and enforces the trademark "Hudson" in the context of continuous integration software, and they say "Stop using the name Hudson", you must comply regardless of any copyright licensing in effect.
Compare Firefox which has a free software license but prohibits use of the Firefox name if any modifications are made to the code. This is why it's called Iceweasel on Debian -- as I understand it, even a security patch is technically enough to violate the contract.
