<overview>
<p>
The Enterprise JavaBeans 3.0 core specification, Section 21.1.2, states:
</p>
<blockquote>
<p>
The enterprise bean must not attempt to manage threads. The enterprise bean must not attempt
to start, stop, suspend, or resume a thread, or to change a thread's priority or name. The
enterprise bean must not attempt to manage thread groups.
</p>
<p>
These functions are reserved for the EJB container. Allowing the enterprise bean to manage threads
would decrease the container's ability to properly manage the runtime environment.
</p>
