+<p>NOTE: the fix for issue 249 (as well as 160) was to disable the
+"sole user" optimization, which was originally done to optimize the
+updating of
+frequently changing appearance attributes in cases where there was only
+one Shape3D using a particular Appearance. This optimization came at
+the expense of rendering performance in some cases, and was also the
+source of several
+bugs. Now that this optimization is disabled, rendering
+performance and stability should improve for most applications, but
+some
+applications may notice a slow-down in update performance. For this
+reason, we have added a new system property to re-enable the sole-user
+optimization.<br>
+</p>
+<ul>
+ <li><code>j3d.allowSoleUser</code> &#8211; If this flag is set to
+true, the 1.4.0-fcs behavior is restored, causing the sole-user
+optimization to be allowed when appropriate. The default value is false.<br>
+ </li>
+</ul>
