Correct me if I'm wrong, but Velocity doesn't stream it's output until the whole template has been satisfied. Therefore, if you are creating a very large response with a template, then it builds the whole response in memory before sending it out. Therefore, it doesn't matter what you set your VM memory constraints to, you will always stand a chance of exhausting the memory.

I'm familiar with the open source Display Table tag library, but not with anything in Velocity of that name...
