Java Garbage Collection details - "Garbage First" G1

For folks into the details of java, there's an interesting blog entry called "Our Collectors" over at Jon Masamitsu's blog, who apparently is a Sun GC guru. It has a nice low-down over the different collectors - what they are, where they are used, and how they can be combined.

Also, this is a good place for some insight into the G1 GC - "Garbage First", a new algorithm that is going to be the default in Java 7.

Some interesting discussion ensues, where Tony Printezis, apparently another Sun insider, chips in with comments.

Also, don't miss this good whitepaper, Memory Management in the Java HotSpot™ Virtual Machine (pdf, April 2006).
