java.lang.OutOfMemoryError: Java heap space for set.mm

I'm using Mac. I followed the Mac OS-X instructions in QuickStart.html. I downloaded http://us2.metamath.org:88/ocat/mmj2/mmj2.zip. I extracted to Users/Userone. I also downloaded http://us2.metamath.org:8888/metamath/set.mm and put it in Users/Userone/metamath.

I right-click on MacMMJ2.command. I choose Open With > Terminal.app.

I get an error: java.lang.OutOfMemoryError: Java heap space

QuickStart.html says set.mm is 6 MB. The one I downloaded is 32.3 MB. Perhaps that's the problem.

Here's the full output:

Jareds-MacBook-Pro:~ jared$ /Users/mmj2/mmj2jar/MacMMJ2.command ; exit;

I assume I can increase JVM memory. But I assume you want your software to just work out of the box, so I'm letting you know :) (Alternatively let me know what I'm doing wrong)
