I can't say that I am familiar with the usage of the "dependencyManagement"

maven reference for this section only talks about it's use in multi-module
projects, so I'm not sure what you are explaining here.
Explaining powerful tools is almost always complex. Maven is no
exception. :-)
"Dependency Management" is useful to resolve version conflicts in your
dependencies.
Let's say you have an artefact A having dependencies on artefacts B and C.
B and C have dependencies on artefact D v1 and D v2
The graph would look like :
A -> B -> D v1
|-> C -> D v2
When you build your project, typically your war, maven can not guess by
itself which version it should pick. AFAIK, it picks the first requested
in the dependency tree, based on dependency order.
As you are a great programmer, you know all of the libraries and
frameworks you are using. So, you perfectly know D, and you know that
the best option there would be to use v2
So, on A's pom.xml, you would add a dependency management section
ordering that to maven.
In your cas, you would typically add
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.javassist</groupId>
<artifactId>javassist</artifactId>
<version>3.18.1-GA</version>
</dependency>
</dependencies>
</dependencyManagement>
To your pom.xml, as a subelement of <project>
Hope this helps.
"Dependency Management" will make your hands dirty (forcing a version is
opening a door to many problems, as you will forget it one day when you
upgrade the dependencies), but it is just required sometimes in real world.
Of course, it is not always enough. If you have dependencies on two
incompatible versions of a package, this will not help.
To get a more complete explanation, I advise to read
https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html
Hope this helps,
Ludovic
Thanks in advance!

However, there is a version conflict with javassist that I strongly advise
to handle using dependencyManagement, or you will get hard to understand
"bugs". :-)
It seems to me that you do not have a version conflict, but rather that
the jandex jar (and I guess many others) is not in the classpath when your
test is run.
Hope this helps...
