Wicket Pattern to reduce session size

[Gaetan Zoritchak]

Hi all,

I was debugging my sessions size in order to reduce it and I saw that one of
my page spend 20ko because of an dynamic image generated with JFreeChart.
JFreeChart was serialized with my DynamicImageRessource.

My first optimisation is to make JFreeChart a static field initialized in a
static bloc.

Is it an valid way of handling that problem?
