Ubuntu seems to favour OpenJDK/JRE very much over Sun JDK/JRE. Even after I installed Sun JRE, JDK and plugin and spent some time plucking out OpenJDK-related packages, apt-get has installed them back with some packages as a dependency. Can this behaviour be corrected in favour of Sun Java packages? I'd like to have one and only Java stack installed (yes, it's a bit of OCD, but I like to have my systems clean) and want it to be Sun Java.

Update: as Marcos Roriz notes, the problem seems to be in default-jre (on which Java-dependent packages use to depend) pointing to OpenJDK, so the question seems to go about how to hack default-jre/default-jdk to point to Sun Java.
