Disconnected from server
The exception does not tell you that you need Java 8 but instead that Java 8 (class version 52) is too old to run classes compiled by version 55 (i.e. Java 11).
So you need to install JDK 11.

I am installing activemq on a new windows 2016 server. I have installed the latest version of Java "1.8.0_321" and the latest download of activemq "5.17.0", but when I try to start activemq I get this error:

C:\Program Files (x86)\apache-activemq-5.17.0\bin>
The JAVA_HOME variable is set:
Java home variable
When I run
echo %JAVA_HOME%
I get
C:\Program Files (x86)\Java\jre1.8.0_321\bin
From that I would infer that it is correct?
Any ideas please?
It states, on the ActiveMQ home page, that ActiveMQ 5.17.0 release requires JDK 11+.
Your error message indicates the class version number of Java 11, i.e. 55.
Either migrate your code to Java 11 or use ActiveMQ 5.16.4 release which is compatible with Java 8.

I tried to "move" the JDK 13 all the way up in PATH, restarted my PC, but nothing changed. Here is a screenshot :
I then tried to download JRE 13, but can't find it anywhere.
How can i do this ?
I can't update to JDK 14 or up, because i need something that was removed in these versions
As you're compiling without a build environment, you'll need to build with:
javac -target 1.8 -source 1.8 MainClass.java
Java versioning is confusing but stick with 13 until you get used to it.

I've tried installing a newer version of java but nothing has changed.
Java 11 should support file format 55 (https://en.wikipedia.org/wiki/Java_class_file#General_layout). Type java -version on commandline to figure out if you are using the correct installation. If not change your environemnt variables accordingly.
I have created a jar file using JDK 8.0 and I tried to run the jar file in a system which is having JRE 7.0, but I am getting an error like this:

What change am I need to make in my jar file creation. So that it will run without version compatibility?
You need to use the -source option for javac. For example:
javac -source 1.7 foo/Bar.java
In theory you can specify the source and target options separately, but judging by your comment, it sounds like you can't use Java 8 language features at all when targeting 1.7.
Note that this only covers your own source code. If xbasej-20091203.jar was built against Java 8, you'll need to find a version which targets Java 7 instead.
