HardwareSimulator.sh on Ubuntu 16.04 SIGSEGV

[SteveGreen]

Hi there!

My name is Steve, from Canberra, Australia.

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)

Help - very stuck right now!

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!
