Hi

We try to migrate from Wildfly 8.2.0.Final to Wildfly 9.0.0.Final. We face an error when we deploy our apps. With 8.2.0, it works fine. We have to use  a custom load metric so that mod-cluster routes is able as we need.

We get this stack trace:

The configuration looks like this:

<subsystem xmlns="urn:jboss:domain:modcluster:2.0">

                <mod-cluster-config advertise-socket="modcluster" connector="ajp">

                    <dynamic-load-provider>

                        <custom-load-metric class="org.jboss.modcluster.load.metric.impl.MBeanAttributeLoadMetric" capacity="5.0">

                            <property name="pattern" value="com.six_group.ssx.seni.request_portal.metrics:service=InitialDownloadResult"/>

                            <property name="attribute" value="CurrentRequestCount"/>

                        </custom-load-metric>

                        <!--  load-metric type="cpu"/ -->

                    </dynamic-load-provider>

                </mod-cluster-config>

            </subsystem>

Do we have to change the configuration?
