What do you mean that you increased virtual memory? In Java the best
thing to do is increase the heap size.

java -Xms128m -Xmx512m Foo

Maybe you have more than 512M to throw at the problem. If that doesn't
work, then you can change your code to write elements at a time and let
them GC so you won't run out of memory. You just need to do a little
manual work for the root element wrapper.
