> HttpFileContentInfoFactory and WebdavFileContentInfoFactory assume that FileContent#getFile() will always return AbstractFileObject subclass for them.
> However, it may be false assumption:  HttpFileObject or WebdavFileObject may be decorated, so even AbstractFileObject#getFileContent() may be decorated, and this FileContent#getFile() too.
> Patch proposal for HttpFileContentInfoFactory/WebdavFileContentInfoFactory: instead of direct casting FIleObject to AbstractFileObject subclass, use FileObjectUtils.getAbstractFileObject() before casting. This way it is non-intrusive: decorating FileObject#getFileContent() is allowed while no regression occurs.
