Thank you for your quick reply Peter. I was wondering if the article that you cite would have the latest command options for G1. I tried some of the optionsthat worked in JDK1.6_14 but they seem to fail with JDK1.6_30.
I am still tryign to log into the web site that shows your article. Does your article delve into the details to take full advantage of the ergonomics of the newest versions of the JDK1.6?
