as the last instruction before your Java™ program ends.</p>
<div class="section"><div class="note"><span class="notetitle">Note:</span> Avoid using System.exit(0) with servlets because doing so
shuts down the entire Java virtual machine.</div>

<div class="section"><p>IBM<sup>®</sup> Toolbox
for Java connects
to the server with user threads. Because of this, a failure to issue System.exit(0)
may keep your Java program from properly shutting down.</p>
</div>
<div class="section"><p>Using System.exit(0) is not a requirement, but a precaution. There
are times that you must use this command to exit a Java program and it is not problematic to
use System.exit(0) when it is not necessary.</p>
