Description
According to the configuration model, the microprofile-metrics-smallrye subsystem should allow for a null value for `prefix`, but on XP 4.0.1 it will throw NullPointerException on startup/reload if that value is null.
Fails:
<subsystem xmlns="urn:wildfly:microprofile-metrics-smallrye:2.0" security-enabled="false" exposed-subsystems="*"/>
Succeeds:
<subsystem xmlns="urn:wildfly:microprofile-metrics-smallrye:2.0" security-enabled="false" exposed-subsystems="*" prefix="${wildfly.metrics.prefix:jboss}"/>
And the error which is shown in the logs:
