[Springframework-developer] Simplification of Spring JMX

[Rob H. <ro...@ca...>]

All,

I am considering removing the notion of the MBeanInvoker from Spring JMX 
along with the Spring implementation of ModelMBean. There are two 
reasons for this:

1. I am not sure of the value offered by this approach given that the 
performance difference between the JDK invoker and the CGLIB invoker is 
hardly noticeable as shown by the tests in the sandbox.
2. All JMX implementations come with RequiredModelMBean which is already 
supported by Spring JMX - we don't really need another implementation if 
there is no benefit and I would prefer not to have keep modifying the 
ModelMBeanImpl class to keep up with the JMX spec.

Originally, I had thought that having our own ModelMBean would enable us 
to improve performance but that turns out not to be true, instead we 
just have a model that is more complicated. I propose to remove the 
MBeanInvoker concept altogether and use the RequiredModelMBean class as 
the standard but provide the ability for other implementations to be 
plugged in a later date should the need arise in the future.

What are your thoughts?

Rob

P.S. - Keith - I know you said this from the beginning and you were 
right. Don't say I told you so :)
