This is how I understood slide 11 of 040-Microkernel.ppt. It's not clear
that it's true only for mbeans from the same -service.xml.
Create is called when all bean I depend on are “created”
When a service's create method is called:
- This gives an MBean an opportunity to check that required MBeans or
resources exist.
- The service typically cannot utilize other MBean services at this
point, as most JBoss MBean services do not become fully functional until
they have been started via their start method.
- Because of this, service implementations often do not implement create
in favor of just the start method because that is the first point at
which the service can be fully functional.

According to our training material, in create a service can check that
the services it depends on exist. In your case, B can check that A exists.
If the training material says that, then it is wrong.
That never has been the case.
Such a check would only work reliably if the two services were
listed in the same -service.xml and the dependee (the first service)
had no other unsatisfied dependencies.
