Unable to access jarfile [NEWB]

OS - Mint 18.1 Serena

The instructions state that I should see the following output after the java -version command.

java version "1.60_65" Java (TM) SE Runtime Environment (build 1.6.0_65-b14-466.1-11M4716) Java HotSpot (TM) 64-Bit Server VM (build 20.65-b04-466.1, mixed mode)

Instead, I received

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)

After downloading and attempting to install the metabase.jar file I receive the following output:

Unable to access jarfile metabase.jar

I’m not entirely sure what to do, any suggestions?

Is there a specific reason you’re using OpenJDK 9? It’s not even released – http://openjdk.java.net/projects/jdk9/

Unless you have a strong reason, we’d recommend using the latest stable Sun or OpenJDK java runtime.
