Let's say we have a POJO A which extends a class B. The start/stop
methods are defined in the class B. In the jboss-beans.xml file is
something like this:

<bean name="A" class="blah.blah.A"/>

Then, only the constructor of A is invoked by AS7, but no invocation of
start/stop methods occur. The start/stop methods are invoked only if
they are directly defined in A.
