Well it appears that this revision is not a one to ignore if you care about performance (and you have the guts of an early adapter:-) The "small" revision update is not small at all and contains 3 important performance improvements:
1. The long anticipated G1 garbage collector
2. Escape analysis
3. Compressed OOPs
I will elaborate on these features in my next posts.... for now you may look at http://java.sun.com/javase/6/webnotes/6u14.html
What does this say about JDK1.7 ? Down porting features before 1.7 is released...... makes you wonder is 1.7 going to be Sun's Vista?
