Unable to install on OSX 10.9

I downloaded the MKL for OSX but am unable to install it. Clicking on the installer opens an empty window with all buttons greyed out. I tried running the installer form the command line and the problem seems to be connected to Java:

$ ./install.sh
In JPanelLicenseOptions
Inside JPanelRegistrationBegin
Calling initComponents
Calling initializePanel

I am running OSX 10.9 and Java 1.8_066-b17.

As a side comment, using this forum is quite frustrating. I'm unable to attach an image to my post with Safari and I've lost my post twice already while trying.
