Utility for detecting and accessing JBoss VFS in the classpath.

<p>As of Spring 4.0, this class supports VFS 3.x on JBoss AS 6+
(package {@code org.jboss.vfs}) and is in particular compatible with
JBoss AS 7 and WildFly 8+.

<p>Thanks go to Marius Bogoevici for the initial patch.
<b>Note:</b> This is an internal class and should not be used outside the framework.
