Hi Andrea, I think the problem is that there really aren't a lot of people working directly on the JDK any more with direct experience with rasterizers. For my day to day responsibilities, I have been officially working on JavaFX for a couple of years, but I am also the engineer with the most

Hi all, it's been a few months since my last mail. If you remember, I've tried participating to Laurent webrev discussions by providing a real world benchmark using GeoServer running the public OSGeo WMS shootout. If you want to read the last discussion on the topic, this was the thread:
