Our Pipelines are running well on Java 11 and we're starting to switch to Java 17. One issue we found is that the Nexus IQ Policy Evaluation throws an "InaccessibleObjectException", probably coming from the xstream library, here's the full error message:
java.lang.reflect.InaccessibleObjectException: Unable to make field protected volatile java.util.Properties java.util.Properties.defaults accessible: module java.base does not "opens java.util" to unnamed module @11cbf98a

Is this bug a known incompatibility or do we have to change settings/parameters to make it work?

We already tried setting Java-Options for the whole VM (see screenshot) like suggested in some threads.

This is our call: 
def policyEvaluation = nexusPolicyEvaluation advancedProperties: '', failBuildOnNetworkError: false, iqApplication: name, iqStage: iqStage, jobCredentialsId: redacted
