Just started this course today. Looks great so far. However, I can't get the HardwareSimulator to fire up. Gives the following error:
# A fatal error has been detected by the Java Runtime Environment:

My java version is:
steve@chuthulu:~/Coursera/nand2tetris/tools$ java -version
openjdk version "9-internal"
OpenJDK Runtime Environment (build 9-internal+0-2016-04-14-195246.buildd.src)
OpenJDK 64-Bit Server VM (build 9-internal+0-2016-04-14-195246.buildd.src, mixed mode)
Java 9 isn't released yet. The one included in Ubuntu is a preview. Please try with Java 7 or 8.
I'm using Oracle JDK 8 on Ubuntu 16.04 (64 bit) and it works fine. It should work with OpenJDK as well, but if you want to use Oracle's I highly recommend this article. It is a bit old, but the PPA is regularly updated.
Thanks dude! You're a life saver. I did end up getting it working in
Windows 7 inside of VirtualBox, but I'd much rather run it on the
host OS, Ubuntu.
Woo Hoo ... now to build those gates!
