Follow-Up Ticket from https://github.com/jenkinsci/performance-signature-dynatrace-plugin/pull/7#issuecomment-466011043 and https://issues.jenkins-ci.org/browse/JENKINS-55202

We are still having missing JAXB dependency exceptions, although we have a dependency to the jaxb-plugin:2.3.0.

I created a test case to reproduce this issue:

1. docker run -p 8080:8080 -p 50000:50000 jenkins/jenkins:2.165-jdk11
2. install Dynatrace AppMon plugin from Jenkins Update Center
3. go to global configuration and add a Dynatrace Server
   Name: Demo
   Endpoint: https://demo6880830.mockable.io
   Credentials: just create some dummy credentials
   System Profile: use the existing one
4. Create a FreeStyleProject and add the "Start Dynatrace session recording" Step.
5. Save and Build the Job.
6. You will be facing the "javax.xml.bind.JAXBException: Implementation of JAXB-API has not been found on module path or classpath." exception
