Many binaries of the icedtea-3 package contain references to icedtea-2, which was used to build it. Because of these references users of icedtea-3 have to *also* download icedtea-2. And because icedtea-2 contains references to icedtea-1, they *also* need to download that version.
It is possible that icedtea-1 contains references to the bootstrap JDK, which will then also have to be downloaded. We should figure out a way to remove all of these references. -- Ricardo
