This is exactly what will happen - remove AOP - if we disable it by 
default and re-write lifecycle handling to plain OO, w/o any costly 
pointcut matching.

The only cost is lookup for potential @AOPEnable on the bean.
While we still keep optional cool feature of creating an AOP proxy for a 
bean.

Regularly?
If you mean to register an mbean, that is actually not what we/users want.
See my response to Dimitris this morning.

While this could be a deployer feature, I think it's far more complex to 
do it than tie it into the bean's lifecycle.
e.g. scan for @JMX, remembering the handle, checking if it's overridden 
for an instance, ... while we already have all this implemented in 
bean's lifecycle handling, it's just not optimized yet.

What do you mean by "similarly with lifecycle and other features"?
@JMX, @JNDI, @Password, ... is the lifecycle callback.

Excellent.
So will I and the rest of MC team.
