How to use Typesafe Stack deb repo with Oracle Java 6 instead of OpenJDK?

I'd like to install Typesafe Stack to Ubuntu Server via their Deb repo, but without downloading all the OpenJDK packages. I have Oracle JDK 6 installed and in my PATH via update-alternatives and installing OpenJDK breaks some stuff.

What would be the best way to do this? It doesn't appear that I can use apt-get --no-install-recommends flag for this:

$> sudo apt-get install --no-install-recommends typesafe-stack sbt

PS - I know the Typesafe Stack components work with my current setup, since I had it installed and running fine with their prior installer.

Old question, has been answered for a long time now in my comments under my OP, just making it official now. On Debian-based systems just use Debian Alternatives, see setup scripts in my comments above. It's brilliant, just works, and provides the following benefits:

1. Use the exact version of Java/Scala/Haskell/etc you want, not what's in the Debian/Ubuntu/etc repos. Useful when the repo version lags the current version, or your app requires a specific version of the platform different from the repo.
2. Haskell platform. Install multiple GHC and Haskell Platform versions side-by-side, say in /opt/haskell/ghc/[version] and /opt/haskell/platform/[version], and easily toggle between them with update-alternatives --config. Same with Java, Scala, or any other sdk/platform.
3. Upgrade to new versions of GHC and Haskell Platform (or Java, Scala, etc) without overwriting or deleting the previous. If this causes regressions in your apps, easily roll back to the prior working version with a simple update-alternatives --config.
4. Keep all files of GHC and Haskell Platform together in a single location like /opt/haskell/ghc/[version] and /opt/haskell/platform/[version], instead of spread out over /usr/bin, /usr/lib, and /usr/share as with an apt-get or dpkg -i installation. The files are kept in /opt/haskell/ and update-alternatives soft links them to their system directories.
5. Easily uninstall with update-alternatives --remove-all (script included), and rm -rf /opt/haskell.
6. Run haskell via system PATH instead of user PATH (eg, no need to add /opt/haskell/ghc/bin to your PATH in .profile)
7. Get used to using update-alternatives, it's a great tool that makes managing manually installed, multi-version software painless. Java, Scala, and any other binary or compiled platform all work equally well with it.
