I tried to compile nodebox on my old Macbook, that is now running Ubuntu 12.04 LTS, but after running ant run, I got these errors:

[javac] warning: [options] bootstrap class path not set in conjunction with -source 1.6
[javac] error: error reading /usr/lib/jvm/java-7-openjdk-i386/lib/ct.sym; cannot read zip file entry
[javac] Fatal Error: Unable to find package java.lang in classpath or bootclasspath
/home/szmarci/Documents/nodebox/build.xml:104: Compile failed; see the compiler error output for details.

Do you have any idea what is the problem?

    It looks like there's something wrong with your Java install, not specifically related to NodeBox.

    Could you try reinstalling the package. Try:

    sudo apt-get --reinstall install openjdk-7-jdk
