For now I am so far:

java version "1.7.0_75"
Java(TM) SE Runtime Environment (build 1.7.0_75-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.75-b04, mixed mode)
Nexuskillers-MacBook-Pro:~ nexuskiller$ cd /Library/Java/JavaVirtualMachines
Nexuskillers-MacBook-Pro:JavaVirtualMachines nexuskiller$ ls

/Library/Java/JavaVirtualMachines/jdk1.7.0_75.jdk/Contents/Home

And after istalling the Java 8 JDK I am here:

Nexuskillers-MacBook-Pro:~ nexuskiller$ java -versions
Unrecognized option: -versions
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

I I go to the /Library/Java/JavaVirtualMachines and hit verbose I see the version I need:

Nexuskillers-MacBook-Pro:JavaVirtualMachines nexuskiller$ /usr/libexec/java_home -verbose

    1.8.0_60, x86_64:   "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home

    1.6.0_65-b14-466.1, i386:   "Java SE 6" /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

Now I am confused ....

Hi, The part where you said:

"And after istalling the Java 8 JDK I am here: ".

It looks like you mistyped the command: it should be java -version NOT java -versions

But even after typing java -version it is not showing your new 1.8 JRE that you installed?
