Snow Leopard (OS X 10.6) is here, and that’s plenty exciting. All the refinements—in the UI and under the good—are getting their due play1. One of those refinements: all of Java’s roads lead to 64-bit Java SE 62.

If you’re not panicking (or at least a little alarmed) then don’t bother reading onward.
