Managing (JMX) Configuration/Policy Beans

[Soltysik, Seumas]

It seems like it would be a good idea to be able to modify certain runtime 
attributes associated with the config/policy Spring Beans via JMX. Since only 
certain attributes make sense to modify at runtime, only these certain 
attributes should be exposed via an MBean. Could we integrate the information 
regarding which attributes should be exposed by annotating the existing schemas 
for the policies and then modifying the JAXB code generator to add JMX 
annotations to the appropriate getter/setter methods? This way we can ensure 
that only certain appropriate values can be changed via JMX.
