I saw your blog. One question for you if you're using GAE/J: how heavy it is the GAE/J warm-up compare to GAE/Python?

I heard stories where some people that use Spring MVC would have their request fails because the call stack is too deep.

Java is heavy, but there are ways to work around it.

The worst offender is the data access libraries. JPA is bad, JDP slightly better, but something like Objectify works really well.

Typically, Spring isn't the problem (I guess it could be if it is doing a lot of classpath scanning stuff or something though)
