CentOS is pretty awesome. I do most of my work these thankfully on a Linux distro. We usually just run command line, and use tools like XMing and Putty to do the GUI only bits of the install.

In this particular install, we were using the Servers GNOME desktop. When running installation manager, we were getting a JVM crash when hitting “Next” on the install for Installation manager 1.8.

After much searching, ensuring everything was up to date I stumbles across this technote.

Once this fix was in place, I was able to continue the install.
