User Boris Pran (https://github.com/borispran) reported the following in a wildfly.org github issue ( https://github.com/wildfly/wildfly.org/issues/796 ):
On Wildfly 36, enable micrometer extension and configure context
/extension=org.wildfly.extension.micrometer:add /subsystem=micrometer:add() /subsystem=micrometer/registry=prometheus:add(context=/prometheus)
than try to get metrics i.e. http://localhost:9990/prometheus and you'll get Internal Server Error!
09:30:37,817 ERROR [io.undertow.request] (management task-6) UT005071: Undertow request failed HttpServerExchange{ GET /prometheus}: java.lang.IllegalArgumentException: -1.0: counters cannot have a negative value

When I get metrics from {}/metrics{} I can see that there is more than one counter with -1.0 value
