I've seen similar errors when executing tests under Java 11. I don't 
remember the exact reason, but I guess it was one of the following:
- features available in Java 8 that were removed in Java 11
- improper module descriptor
- for example missing dependencies such as 
jakarta.xml.bind:jakarta.xml.bind-api in your pom.xml when you're using 
JAXB in your code
