<div class="block">Bundle Revision. When a bundle is installed and each time a bundle is
updated, a new bundle revision of the bundle is created. Since a bundle
update can change the entries in a bundle, different bundle wirings for the
same bundle can be associated with different bundle revisions.
<p>
For a bundle that has not been uninstalled, the most recent bundle revision
is defined to be the current bundle revision. A bundle in the UNINSTALLED
state does not have a current revision. The current bundle revision for a
bundle can be obtained by calling <a href="../../../../org/osgi/framework/Bundle.html#adapt(java.lang.Class)"><code>bundle.adapt</code></a>
(BundleRevision.class). Since a bundle in the UNINSTALLED state does not have
a current revision, adapting such a bundle returns <code>null</code>.
