`NoSuchMethod` error when trying to run tests

[eheinlein-verta]

I'm working on installing this to test our SCIM implementation. However, I am getting an error when I try to run the tests from the main test page. My best guess is that this is caused by a conflict in the ReflectionHelper classes - one in info.simplecloud.core.coding and one in com.sun.jersey.core.reflection.

Steps I used to reproduce:

• Follow the installation instructions, using Tomcat 8.5.72 and Java 17.
• On the index page of the test app, enter the required information (URL and authentication method - in my case a bearer token)
• Click "Go!"

Expected: the tests run
Actual: a red bar is shown with no text; a POST to http://localhost:8080/scimproxycompliance/compliance2/test2 has returned 500, with the stack trace below in the server logs.

I've tested a few things along the way; I initially used Tomcat v10.0.12 installation but had issues, so I downgraded). I've tried some different versions of jersey in pom.xml. (I tried 1.17.1 because I saw that version a lot when googling tomcat setup issues, and also 1.19.4, which is the latest). I can't try a different version of info.simplecloud.core.coding because it's included as a jar and it doesn't seem to be distributed elsewhere.

Has this been reported before? Have I missed a step?
