<overview>
<p>
The Enterprise JavaBeans 3.0 core specification, Section 21.1.2, states:
</p>

<blockquote>
<p>
The enterprise bean must not attempt to create a class loader; obtain the current class loader;
set the context class loader; set security manager; create a new security manager; stop the
JVM; or change the input, output, and error streams.
</p>
<p>
These functions are reserved for the EJB container. Allowing the enterprise bean to use these functions
could compromise security and decrease the container's ability to properly manage the runtime environment.
</p>
</blockquote>
