DIY Book Scanner

I've done a video that goes over the basics:

Hi guys,
Am finding Book scan wizzard to have alot of promise in terms of increasing the efficiency of my post processing but haven't gotten it to work properly yet.
The problem is i keep getting an error.

java.until.concurrent.ExecutionException:java.lang.OutOfMemoryError: Java Heap space

I have shut down all applications and tried the software on multiple machines with large ammounts of RAM eg 16gb.

Is there something i may be doing wrong that is triggering this?

Any help would be appreciated. Thanks!

What kind of processor do you have? Do you know how many cores it has?

What operating system? (Windows, Linux, or Mac)

How many megapixels are your source pictures?

Are you starting the program using webstart?

I've been using the downloaded version, ie the zip from source forge. Using windows 8 on Samsung slate 7. So i think its a dual core, 1.7 ghz.
The images are 8 mega pixel. I'm going to try the web start version and see how that goes.

Webstart seems to be working.
