 public Object clone() 
{
        if (isReference()) {

{
        return true;
}

Always returns true.

 public Iterator iterator() 
{
        if (isReference()) {
            return ((DirSet) getRef(getProject())).iterator();
        }
        return new FileResourceIterator(getDir(getProject()),
            getDirectoryScanner(getProject()).getIncludedDirectories());
}

 public int size() 
{
        if (isReference()) {
            return ((DirSet) getRef(getProject())).size();

        return getDirectoryScanner(getProject()).getIncludedDirsCount();
}

{
        DirectoryScanner ds = getDirectoryScanner(getProject());
        String[] dirs = ds.getIncludedDirectories();
        StringBuffer sb = new StringBuffer();
        for (int i = 0; i <  dirs.length; i++) {
            if (i  > 0) {
                sb.append(';");
