I'm asking this because Libre Office was pre-installed and some of it's features require Java. I don't want Java because of a malicious remote administration tool (RAT) called jRAT and there are also others. But with this even a script kiddie can take control of my computer.

Simple answer, Java is not installed by default in any Ubuntu system (in fact this goes against the Java distribution policy, that's why is being included in the non-free repository).

You can check the packages manifest of any version of Ubuntu, and you will notice that it does not include either JDK nor Java.

Precise Pangolin package manifest:

http://releases.ubuntu.com/releases/precise/ubuntu-12.04.3-desktop-i386.manifest

Raring Ringtail package manifest:

http://releases.ubuntu.com/releases/raring/ubuntu-13.04-desktop-i386.manifest

You can search the list up and down, and you will find no reference to Java (please don't confuse with JavaScript, that is different).

  • How does LibreOffice run, then?

    libreoffice suggest the package java-runtime for some specifics functions but isn't necessary the complete Java Virtual Machine. It also includes their very own packages with Java classes, scripts, and config snippets called libreoffice-java-common, but not all the suite require the packages (only writer and base). Hence, you can use most of LO without even installing Oracle's Java or openJDK.

  • Do you just mean Oracle Java is not installed? Is OpenJDK also not present?

    This was answered above:

Hope this address all inquiries.
