How do I change the Java Virtual Machine installation the MATLAB installer uses?

I would like to tell the MATLAB installer to use a different installation of java than it comes packaged with. How would I do this? What is the default java it uses?

To change the java version the installer uses, you need to add the following flag to the installer:

-javadir <directory>

(Where <directory> is, put the full path to your java installation folder.)

For example,

On Windows:

 setup.exe -javadir "C:\Program Files\Java\jre6"

On Mac:

 ./install -javadir /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home -v

On Linux:

 ./install -javadir /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/

If the flag isn’t used, the default java shipped with the installer is used:

 -javadir <installer>/java/jre/$ARCH/jre/

(where <installer> is the location of the installation files, and $ARCH is the architecture, win32 for example)
