Java News from Tuesday, February 17, 2004

Excelsior has posted the fifth beta of JET 3.5, Professional Edition, for Linux. Excelsior JET is a Java virtual machine that uses a combination of a traditional native code compiler amd just-in-time compilation from byte code. JET costs start at $750 and run up to $2300 depending on how much support you want.

Support is available by e-mail and Web site only. Personally, if I'm paying over $2000 for support, I expect to be able to pick up the phone and talk to someone NOW when I have a problem, rather than being dumped in an e-mail queue. E-mail support is fine, and should be offered too for those times where it's more convenient, but it should not be the only means of support. One more time: I don't mind paying for software, but if a company expects me to buy their product instead of using a free-beer or open source alternative, they MUST provide significantly better support than I can get from a Usenet newsgroup. In most cases including Java VMs, the quality difference between the payware products and and the free-beer and open source alternatives has dwindled to next to nothing. Almost the only differentiator a software company can add to justify their product is excellent support. When software companies cut their costs by limiting support, I cut my costs by not buying their products.

YourKit, LLC has released YourKit Java Profiler 2.0.1, a 295€ payware tool for detecting memory leaks and memory consumption bottlenecks. It features Automation of memory leak detection, an object heap browser, JUnit integration, IntelliJ IDEA Borland JBuilder integration. Version 2.0.1 is a bug fix release. Upgrades from version 1.0 (when it was called the YourKit Memory Profiler) are 140€. The tool runs on Windows or Linux.

William Ready has released JWizardComponent 1.2.2, an open source Swing component that presents information to the user in a step-by-step manner such as those used in many installers. JWizardComponent is published under the LGPL.

Nathan Fiedler has released version 2.21 of JSwat, a graphical, stand-alone Java debugger built on top of the Java Platform Debugger Architecture. Features include breakpoints, source code viewing, single-stepping, watching variables, viewing stack frames, and printing variables. Version 2.21 adds launcher scripts for Unix and Windows. It also fixes several bugs. JSwat is published under the GPL.
