Making your components work nicer inside Matisse: Have you developed the killer component for your application, but it takes too long to load inside Matisse? Or worse - you face class loading errors since it has too many weird dependencies? Well, here is a small tip to make it work faster and without much hassle...

A public pledge to NetBeans: I could not be more disappointed after attending the Swing GUI Building With Matisse: Chapter II presented at NetBeans. It's not a problem with the Swing Application Framework or the NetBeans tooling; it's a problem with freedom of choice, vendor lock-in and a close-minded approach, not community-friendly held by the NetBeans guys.

Displaying messages in the system tray: You probably have seen messages popping up in the system tray (or status area), such as "Low battery" or "Updates are ready to be installed", produced by system tray icons. Did you know it is possible to show these messages with Java SE 6?

Swing made easy with genesis: In the beginning, developing with Swing was a pain. It was hard to assemble an interface and even harder to program it. Then, Matisse appeared, and as more people could design their interface, more and more asked, 'hey, but how can I make it work for real now'? The answer is in genesis ;-)

Branching open-source software: a bad thing?: Using open-source frameworks and tools already available instead of rolling your own solution is a good thing. However, what happens when you find out you can't solve a problem by extending a class or changing some configurations? What if you write a patch to a problem and no one commits it after weeks? Is it a good thing to start branching nearly every library and tool you need to use?

Things that could be different - Part 1: Exceptions: Java is notably the first programming language to provide full support for checked exceptions - you must explicitly declare them if you they are going to be thrown, you are forced to either handle or declare to throw them and more. However, after using them for a while, you start noticing that sometimes things don't work so well. I do like checked exceptions, but read this blog entry for some of my thoughts about how exceptions could be different (and sometimes, better)...

It took me no more than a few minutes to figure out the strange issue you will read about, but it was an akward experience, actually.
