Hi,
                I'm using Commons VFS inside an Apache Pivot remote file br=
owser and I'm getting a strange result when switching between different HDF=
S hosts.  I have two FileObjects, with different host:port (but the same di=
rectory name), and they compare equal (i.e., the FileObject.equals(...) met=
hod returns true, when they are clearly not the same.  Any thoughts?
                Here is the code and my results:
System.out.format("VFSBrowserSheet.setRootDirectory: does '%1$s' exist()? %=
2$s%n", rootDirectory, rootDirectory.exists());
        if (rootDirectory.exists()) {
            FileObject previousRootDirectory =3D this.rootDirectory;

System.out.format("VFSBrowserSheet.setRootDirectory: previousRootDirectory =
=3D %1$s%n", previousRootDirectory);
System.out.format("VFSBrowserSheet.setRootDirectory: rootDirectory[%1$s].eq=
uals(previousRootDirectory[%2$s])? %3$s%n", rootDirectory, previousRootDire=
ctory, rootDirectory.equals(previousRootDirectory));
            if (!rootDirectory.equals(previousRootDirectory)) {
                this.rootDirectory =3D rootDirectory;
                selectedFiles.clear();
System.out.format("VFSBrowserSheet.setRootDirectory, calling 'rootDirectory=
Changed'%n");
                fileBrowserSheetListeners.rootDirectoryChanged(this, previo=
usRootDirectory);
            }

VFSBrowserSheet.setRootDirectory: does 'hdfs://chhadoop-master:9000/' exist=
()? true
VFSBrowserSheet.setRootDirectory: previousRootDirectory =3D hdfs://chcluste=
r2-master:8020/
VFSBrowserSheet.setRootDirectory: rootDirectory[hdfs://chhadoop-master:9000=
/].equals(previousRootDirectory[hdfs://chcluster2-master:8020/])? True

Thanks,
~Roger Whitcomb
