Understanding the Interplay Between Utility Classes and Static Initialization Using static initializers is a common practice for setting up fields that need to be accessed from distantly related classes. However, without a firm understanding of how statics work with relation to subclassing, and a careful establishment of initialization expectations, difficult problems can arise. Satya Komatineni offers a new pattern that can reduce these problems. [ONJava.com]
JDemo: Interactive Testing Refactored The nature of GUI development doesn't lend itself to test-oriented methodologies very well. But that doesn't mean you shouldn't test your components!

[Source: Java Wireless Technology Highlights] Is Sun Turning against Linux and Red Hat? An Elephant writes "Groklaw is reporting, based on a ZDNet UK story, that Sun's strategy for survival in the near future is based on trying to equate Linux with Red Hat, and then attack Red Hat as too small to support enterprises. This seems strange -- Sun is selling a Linux distro itself (the Java Desktop System). As I write this, there's no mention of this on Sun's website -- neither confirmation nor denial. What's going on?" [Source: Slashdot Org latest news headlines] Spam Opt-out Link Triggers Malicious Code Attack Maestro4k writes "The Register is reporting on a new spam E-mail circulating out there. In it, clicking on the 'Click here to remove' link launches a site, that when the user scrolls the page, triggers a drag-drop javascript exploit. Scarily the E-mail actually complies with the CAN-SPAM act as it only requires spammers to put an opt-out link in their mailings. As The Reg says "It comes as little surprise that this feature is been taken advantage of in a social engineering exploit; but it does illustrate the security problems of the opt-out approach that were always apparent to security experts - and ignored by legislators." The link in questions points to www. xcelent.biz (As in The Reg story, space intentionally included) so even if you can't block the mail yet it should be easy to block access to the site with the exploit. I suspect this is just the beginning and most spam will include "features" such as this in the near future."
