>    Affects Versions: 1.4.0, 1.5.0

>             Fix For: 1.5.3

> Hi,
> in BrowserConnectionManager.load
> and in
> Utils.serialize / deserialize
> we recognized that the ClassLoader is modified without conserving / resetting it to the previous one at the end.
> This conflicted with our class loading mechanisms ... streaming from our own class store.
> As a quick fix for testing, we could do for example the following; however, this is not a real solution:
>     public static String serialize( Object o )
>     {
>     	String s = null;
>         Thread cur_thrd = Thread.currentThread(); //patch reset current class loader
>         ClassLoader cur_thrd_cl = cur_thrd.getContextClassLoader();
>         try{
> 	        cur_thrd.setContextClassLoader( Utils.class.getClassLoader() );
> 	        ByteArrayOutputStream baos = new ByteArrayOutputStream();
> 	        XMLEncoder encoder = new XMLEncoder( baos );
> 	        encoder.writeObject( o );
> 	        encoder.close();
> 	        s = LdifUtils.utf8decode( baos.toByteArray() );
>         }finally{
>             cur_thrd.setContextClassLoader(cur_thrd_cl);
>         }
>         return s;
>     }
> => Is there a better way?
> Thanks and regards,
> Karsten
