    Description

      A user encountered the following error when attempting to start EAP 5.0.0 w/mod_cluster 1.1.0.Beta1:

      09:25:15,078 ERROR [AbstractKernelController] Error installing to Instantiated: name=ModClusterService state=Described mode=On Demand requiredState=Installed
      java.lang.IllegalArgumentException: Wrong arguments. new for target java.lang.reflect.Constructor expected=[org.jboss.modcluster.config.ModClusterConfig, org.jboss.modcluster.load.LoadBalanceFactorProviderFactory] actual=[org.jboss.modcluster.config.ha.HAModClusterConfig, org.jboss.modcluster.load.impl.DynamicLoadBalanceFactorProvider]
      at org.jboss.reflect.plugins.introspection.ReflectionUtils.handleErrors(ReflectionUtils.java:395)

      The microcontainer is trying to instantiate ModClusterService using the wrong constructor. The mod_cluster-jboss-beans.xml should be updated to explicitly define the parameter types to remove this ambiguity.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
