I'm using docker image: camunda/camunda-bpm-platform:wildfly-7.14.0

sun.misc.is available for Java <= 8 java.util.is available in Java >= 8

You can try changing the version of the Prometheus dependency jar to a version that supports your needs. Can you test with camunda wildly 7.12 and see if you have the same error? Maybe something specific to wildfly.
