introduced in Java SE 7, EJB 3.2 added the implementation of the

interface in the
EJBContainer
class to free the de-
veloper from a task that could easily be forgotten and have negative repercussions
on the performance of a machine. Now, the embeddable
EJBContainer
will be
automatically closed at the end of a statement, provided that it is declared as a re-

The final improvement of this specification concerns removal of the restriction on ob-

system from a bean.
