The reason I'm doing this is to have Sun's java 6 installed (getting updates, etc.)
- In 11.10 Sun's Java was removed from the partner repository.
What do you think are the potential disadvantages?

No disadvantages are guaranteed, but you could easily end up with dependency issues, where one package depends on a different version of a library than another package, so it could mess up your system updates or trying to install certain applications. Regarding Java, as mentionned already, try to follow alternative instructions from blogs to download individual packages from an older version of Ubuntu rather than adding old repositories.
If you use the natty repos you could potentially damage your system, however here are some instructions found at: How do I install Oracle Java JDK 7?
