## Class VfsUtils

- java.lang.Object
- - org.springframework.core.io.VfsUtils

-     public abstract class VfsUtils
      extends Object

  Utility for detecting the JBoss VFS version available in the classpath. JBoss AS 5+ uses VFS 2.x (package `org.jboss.virtual`) while JBoss AS 6+ uses VFS 3.x (package `org.jboss.vfs`).

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