Description

The latest version from trunk fails to work with Apache Ant resulting in this error:
Could not load VFS configuration from "jar:file:/media/Fort/per/program/backup/lib/commons-vfs-2.0-SNAPSHOT.jar!/org/apache/commons/vfs/impl/providers.xml".

which was caused by
java.lang.ClassNotFoundException: org.apache.commons.vfs.provider.local.DefaultLocalFileProvider

The cause seems to be a class loader issued introduced in rev 537717.

Reverting that change:
cd core
svn diff -c r537717 src/main/java/org/apache/commons/vfs/impl/StandardFileSystemManager.java | patch -R
mvn clean install
[copy commons-vfs-2.0-SNAPSHOT to my test's lib dir]
ant -f test.xml test

Makes my example ant file work again (worked with the 1.0 release).
The 537717 revision was intended to fix
VFS-136: Don't force-set the classloader - Thanks to Adam Heath for the patch

So it might be a bit controversial to reverse that change.
Attaching patch fixing the issue and my example ant file.
