You have probably only installed the JAVA runtime, while for your requirements you need the JAVA Development Kit.

Which version & type of Java instance did you install?   The runtime and development kits are two different beasties.

JRE = Java Runtime Environment
Basically the the Java Virtual Machine

JDK = Java Development Kit
The full feature set for that version of Java

A good explanation can be found here:

download  Java SE Development Kit 8u102 for OSX from http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html and restart your mac book air to take effect.

For my understanding, what is special about the 8u102 version compared to the normal java update messages most people get asked if they want to update?

The Java runtime is a cut down Java that allows you to run java programs. That is what most people have. The Java Development Kit on the other hand is a full Java development tool with which you can create Java Programs.

Why would any other software install I have made, require the development kit version though, I'm not a programmer.

Interactive Brokers.  TWS trade system.

I have looked into the Java requirement for your software listed above and comes up with recommendation in my previous comment.

The concept is that if your software is just a browser based, only Java runtime is needed.

If you need to know why, you need to enroll in a course for Java for one month.

In practice, I just recommend that you look up the requirements for a software and comply with them if you want to use the software.

Good question. Most people just do e-banking and online shopping using the browser. So, only update the Java runtime is enough.

Ask the people who programmed the software you are using why it requires the Development Kit to run.
