This is an important piece of software for many of us, essential for using various pieces of specialised software, however it also needs to be supported. A handful of bugs including one really serious one (ie can bring down your entire graphics system -- don't try resizing a 3D view made using a ConfigureUniverse for example...) have not been fixed in the 18 months since it was released (and yes, I have reported them to Apple).

Java 3D itself has been open source for a while, but that doesn't include the Mac port so we're still dependent on Apple supporting this software. Still. they've surprised me before (by porting Java 3D at all) after I'd given up hoping...

Having said that, this is essential software for using Java 3D applications on the Mac. Just don't resize a window containing a 3D view before saving any important work you have done, in case the programmer happended to use a ConfiguredUniverse class to implement his/her J3D application!
