Just a note to anyone reading this guide, after you have run the following command:

sudo update-alternatives –config java

and chosen the version with 8 in it. Make sure that when you type java -version you notice that it is a single – instead of — in front of version.

I missed this as most flags are now –version etc.

It was giving me an error of “Error: Could not create the Java Virtual Machine” and it just because I was doing java –version instead of java -version.
