/**
* Utility for detecting the JBoss VFS version available in the classpath.
* JBoss AS 5+ uses VFS 2.x (package {@code org.jboss.virtual}) while
* JBoss AS 6+ uses VFS 3.x (package {@code org.jboss.vfs}).
* As of Spring 4.0, supports VFS 3.x on JBoss AS 6+ (package {@code org.jboss.vfs}).
*
* <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.
