Much or less talked about even in the Sun Tech Days event this year is the need for creation of space in jvm library set for dynamic languages/constructs support mainly javascript, python and ruby. Even some unused libraries from core java io/lang/util to be cleaned up for this purpose. As usual none of this is certain but pointers from oracle about where Java is moving towards.
Something I would like to look at would be the image based capability from smalltalk which is such a developer comfort. I would like to write in line and length about it sometime.
