Exception in thread, NoClassDefFoundError in 1.3.1 and 1.4.1RC2

[gerben86]

We're running the Karate test on Linx (via Jenkins) with OpenJDK (and the error is about GraalVM...).
After all tests are finished we're getting this error:

Test run finished after 18014 ms

We didn't have this error on the version 1.1.0, but now we're migrating to 1.3.1 this issues pops up.

Command we're using to run the Karate-tests:
java "-Dtest=RegressionTest" "-Dkarate.env=TST" -jar lib/junit-platform-console-standalone.jar --classpath "karate-1.0-SNAPSHOT-dependencies.jar;karate-1.0-SNAPSHOT-tests.jar" --scan-classpath "--include-package=karate" --fail-if-no-tests --details=verbose --include-classname=^.*Test$ --exclude-engine=junit-vintage

The karate-1.0-SNAPSHOT-dependencies.jar and karate-1.0-SNAPSHOT-tests.jar are created via the maven-assembly-plugin in our pom.xml.
We don't have Maven on the Jenkins-machine, so that's why we're creating to jar's in the Azure-pipeline which deploys it to our Jenkins-machine (Jenkins is only for test-ochestration, not for building/compiling).

I'm a little bit stuck in how to get rid of this error.

@gerben86 I'm sorry I don't think I can help with a custom jar packaging situation. if you can create a minimal way to repro, of course. you can try using the "fatter jar" option: #1916 (comment)
