On Friday, I noticed that starting Java 6, command line classpaths can contain wildcards.
This is very cool! (and about time.) It's helpful when distributing a command line program. Especially with Maven since the jars contain version #s and change often.
(no this isn't a question; I hadn't known about the feature so wanted to post.)

Yeah I was happy when I saw that too. Actually, I forgot that Java didn't support wildchars, and I put wildchars in the classpath by mistake. I ran it, it worked, then I remembered Java doesn't support wildchars. That's when I "discovered" these feature

I was actually looking for whether -cp "commons-io-*;commons-lang-*" was legal so I could at least leave out the version numbers. And found I could specify the whole directory in one go!

yep. nice feature. One important point is that if the order of jars in the folder is important for the application, then wild cards shouldn't be used as the order of loading of Jars may vary for each execution.
