Openjdk7 source package needs update.

[Christophe]

I am trying to compile Openjdk7 from source.
I download the source package from bazaar.launchpad.net with the command:
bzr branch http://bazaar.launchpad.net/~openjdk/openjdk/openjdk7
and I follow the instruction given in the downloaded file tree.
Several informations are not up to date:
* The version of the openjdk (7u73 instead of 7u75)
* The extension of different tarballs (gz instead of bz2)
* Some tarball needed for the main compilation build are not present in the download and are not downloaded by the proposed procedures to collect these tarballs (ex: icedtea-sound.tar.gz)
* This source package is claimed to be the source for debian source packages for openjdk7; well did the Debian team used this package to generate it. If so, please document how to use it!
