Mike is showing majority of clustering tests failing. The root cause is this:

2010-06-10 14:59:44,803 ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] (RMI TCP Connection(3)-127.0.0.1) Error installing to Start: name=ProxyFactory/clusteredsession-test/OverrideStateful/OverrideStatefulRemote/DefaultPartition state=Create: java.lang.NoSuchMethodError: org.jboss.ha.framework.server.HATarget.getReplicants()Ljava/util/ArrayList;

at org.jboss.ejb3.proxy.clustered.factory.session.stateful.StatefulSessionClusteredProxyFactory.start(StatefulSessionClusteredProxyFactory.java:117) [:1.0.3]

The HATarget used to have a:

public ArrayList getReplicants()

in 1.1.1.GA version of jboss-ha-server-api

which has now changed (for good reasons) to:

public List getReplicants()
