<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>
