[xep-support] Java out of memory error

Danny,

I believe you just hit the limitations of current technology. Memory
consumption with huge tables is a painful issue for all Java-based
formatters. There is not much to advise in your case. Just make sure
that common prescriptions are all observed:

- your java call has -Xmx and -Xms switches set to the maximum
value that the RAM of your machine affords (typically, around
200 MB for a machine with 256MB of RAM);

- you use the latest stable JDK release (1.3.1) and HotSpot is turned on;

- your code uses as few tables as possible - e.g. you should never
  use tables to indent text à la HTML;

- if you have longish bulleted/numbered lists, consider restyling
  them with leader-based bullets.

Hope this helps at least to ensure that everything possible has been done :-).

Best regards,
