    Description

      The microprofile-metrics-smallrye subsystem allows an undefined prefix attribute to be added. In the add handler it sets the prefix to null if undefined. However the WildFlyMetricMetadata does not allow a null prefix resulting in a NullPointerException during deploy or boot of the server.
