On a completely tangential note, I think Sun should be thwapped over the head with a cluestick for not following generally-accepted standards for command options. "java -jar" should be either "java -j" or "java --jar". I can't tell you how many times I'm working with WebSphere at work and I type "java --fullversion" to find out what JDK I'm in, only to get this:

Unrecognized option: --fullversion

Could not create the Java virtual machine.

.
I know Java isn't the only software out there that does this, ("xterm -display" is another one that I hate.) But it makes so much more sense to use a single hyphen for single-character options, and a double hyphen for "long" options. Or at the very least they should support both for forgetful schmucks like me who can't remember which program uses which "standard."
