<div class="block">Called when the region containing this callback is closed or destroyed, when the cache is
closed, or when a callback is removed from a region using an <code>AttributesMutator</code>.

Implementations should cleanup any external resources such as database connections. Any runtime
exceptions this method throws will be logged.
<p>
It is possible for this method to be called multiple times on a single callback instance, so
implementations must be tolerant of this.</div>
