DMN: org.kie.dmn.runtime.listeners.$LISTENER_NAME property ignored

Documentation at https://access.redhat.com/documentation/en-us/red_hat_process_automation_manager/7.8/html-single/designing_a_decision_service_using_dmn_models/index#dmn-properties-ref_dmn-models specifies that the "org.kie.dmn.runtime.listeners.$LISTENER_NAME" property can be defined as a startup parameter, e.g. as in "-Dorg.kie.dmn.runtime.listeners.mylistener=org.acme.MyDMNListener" to specify a DMN Event Listener.

However, this parameter seems to be ignored by KIE Server.

Tried by specifying as a command line argumant, as per documentation, and as an EAP system property.

DMN Event Listeners were specified as

• project dependencies in the pom.xml
• in the project "src" directory structure
• also tried with non -existent classes

No event were captured or logs generated nor any exceptions logged.
