So I don't know how Gentoo is currently planning on doing this, but one thing I've noticed with several packages is that if you try and install it, it will exit with a message telling you to go download it from the company however they want you to and stick it in Gentoo's downloaded source directory. (Actually it already does this for the sun-jdk package.) Can't Ubuntu do something similar? Silently removing the package from the repository is one thing and relatively fine; silently removing the actual binaries is another thing and out of the question. That JVM being available may be incredibly important, you have no idea what it's being used for or how susceptible it is to theoretical 0-day JVM vulnerabilities.
