Description

I downloaded the binary James 2.3.0 final release and modified the kernel.xml according to http://wiki.apache.org/james/ConfigureJmx, section Enabling James' built-in MBeanServer. This gives me an exception

Without JMX enabled, James starts just fine.
Copying the jars from the current MX4J release (3.0.1) into lib and bin/lib directories does not help.
Neither does configuring MX4J as the default MBean server via adding -Djavax.management.builder.initial=mx4j.server.MX4JMBeanServerBuilder
to the RUN_CMD in phoenix.sh (as suggested e.g. in http://jira.codehaus.org/browse/LOOM-78). This changes the exception to:
