For what it's worth, I got my new unibody MBP in the mail today... first thing I did was run software update, downloaded 11 (java included) and the java installation failed. Computer restarted, ran a second time and it worked. So I thought it was a one time issue. Turned on my second gen MBP, only update available was the java and it failed as well. Tried again, another fail. Tried a third time, worked like a charm. The two computers were made, what, 3 - 4 years apart? Come on apple, try testing this on a few devices before letting it out the gates. lame.
