[jboss-as7-dev] JMX [was: Dear subsystem owners/components leads ....]

[Eduardo Martins]

With easy extension I mean to be possible for people to add other not
so basic JMX features, to build on top of it, if they really need it.

Now with respect to this stuff becoming an excuse to not use the
management API... I think even 3rd party systems will use it, all
depends on what people get from it, but note they will be developing
on top of something proprietary, that is a "no way" for some 3rd
parties. But for a start, having basic JMX features in the management
tools is a must, very important for easier migrations, not only from
older JBoss AS versions, but also from competing products.

Expose the bait... get people in the shop, then sell what really
matters, otherwise you risk not sell anything at all.
