Anyone interested in brushing up on their Java SE 6 troubleshooting skills might take a look at my article, Chuk-Munn Lee of Sun Microsystems Troubleshoots Java SE 6 Deployment, based on a Tech Days presentation by Java technology evangelist Chuk-Munn Lee, given in Sydney, Australia, in March 2008. The article covers Java SE 6 troubleshooting updates; memory management; tools like jps, jinfo, jstat, JConsole and Java VisualVM; and more. Based in Singapore, Lee works frequently with individual developers and software vendors, helping them to architect and prototype both their server and desktop-based Java applications. He's a sharp guy with a lot of experience. (This Tech Days was my first visit to Sydney, Australia. It's a beautiful, vibrant city. I highly recommend it as a destination.)
