Garbage First - Sun (Server-Centric) Collector Slated For JDK 7

This is very much "hot-of-the-press" for us in the Adobe server-centric space. Sun are currently working on their JDK 7 version, this in itself is not surprising however the focal point of this version is very much directed at the server side. In addition, it looks like they will be introducing a new collector which they are calling "Garbage First". I am still studying this and will blog in greater detail shortly. This is what I have read so far as major features:
- Designed specifically for server applications running on multi-processor systems with large total heap size (think 64-bit).
- The heap is divided in "x" regions which are not hierarchical but concurrent.
- Uses a snapshot at the beginning (SATB) to identify regions that have the least live data as those are more collectible.
As I say, there is much more to study and I hope to be able to add some information to
my presentation at Adobe MAX Europe, in Milan, about this.
