From your edit, it looks like you have two instances of the openJDK installed. If you want them to match, you have two options:

Uninstall the one you don't want. E.g. if you want open-jdk7 but not open-jdk6 do sudo apt-get remove --purge openjdk-6-*

Update the alternatives for java using sudo update-alternatives --config java and pick the one you want. If you need to have both JDKs available, this is your best option as you can then just do that each time you need to switch
