Through JMX page, MDB create/destroy don't work as expected

SourceForge Submitter: genman .

JBoss.3.2 RC1, with jboss.jar from Beta3

Under category jboss.j2ee:

Click on a MDB, click stop. JBoss still sends one more
message to my MDB. (I think that instance is cached.)

Click on destroy, all cached MDB are destroyed, as
expected. Click on create, you get an exception back:

MBeanException: Exception in service lifecyle
operation: create
Cause: java.lang.NullPointerException
at org.jboss.ejb.Container.invoke(Container.java:749)

Click on start:

MBeanException: Exception in service lifecyle
operation: start
Cause: javax.naming.NoInitialContextException: Cannot
instantiate class:
org.jnp.interfaces.NamingContextFactory [Root exception
is java.lang.ClassNotFoundException:
org/jnp/interfaces/NamingContextFactory]
at org.jboss.ejb.Container.invoke(Container.java:749)
