There is a mismatch in terms of dependencies between the mc beans and the legacy jmx beans that affect integration of the bean deployer in jboss-4.0.x. It should be possible to extend the org.jboss.kernel.plugins.deployment.xml.BeanSchemaBinding to add a jmx-depends tag that specifies the jmx mbeans that the org.jboss.kernel.deployment.jboss.JBossBeanDeployment which is registered with the jmx kernel depends on.
