Joerg,

I looked at the patch you supplied.  In the comments below you say...

"The buffer created in AbstractSerializer was actually never used,
 because all subclasses of AbstractSerializer either didn't use
 super.setOutputStream()"

but if you look, all the files you've patched have...

             super.setOutputStream(out);

Am I missing something?

J.
