Jochen Wiedmann resolved FILEUPLOAD-162.

    Resolution: Won't Fix
      Assignee: Jochen Wiedmann

Serializable file items have been a design error right from the start. If you have issues like yours, please use a custom FileItemFactory.

> When I serialize DiskFileItem which are not 'inmemory' and unserialize them back,
> I get a crash in isInMemory, because the file cited in the serialized content have been deleted meanwhile.
> here is a patch I propose
> private void writeObject(ObjectOutputStream out) throws IOException {
> 		// Read the data
> 		cachedContent=get();// get in mem before serialize en mémoire
> 		// write out values
> 		out.defaultWriteObject();
>                 cachedContent=null;//clean mem... not so usefull since object will probably die soon, but...
> 	}
