We make use of the ConcurrentLinkedQueue class, and which is not white-listed like other concurrent collections are. The unmarshalling and marshalling of the field fails with the following error:

java.util.concurrent.ConcurrentLinkedQueue in JRE might be dangerous, so rejecting; see https://jenkins.io/redirect/class-filter/
