We used Pacifist ( http://www.charlessoft.com/ ) to re-install the java Update14
This is shareware and he asks for $20. We are sending him $100!!!!
πππππππππππ -- that's us doing the happy dance!!!
(We have Update15, but, a) apple has removed it from the support downloads site, and b) 16 came really fast after 15 -- so I suspect that 15 is broken somehow. The guessing game is a little annoying -- an article on the support page that would come up when you search for java for 10.6 update 15 saying that apple has removed the update and don't install it if you downloaded it would be, well, courteous!)
Note -- this seems to have worked just fine to clean up whatever update 16 broke for us, but I suspect that we could have used pacifist to install updates 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 and then 14 and been really really likely to undo whatever bad thing update 16 did.
Another note... Got into this mess because I was trying to minimize downtime. I've never had a problem with a java update before so I got greedy/sloppy. Sure plenty of OTHER people have had problems with java updates, but, well, what is that old saying?
Smart People
learn from their mistakes. And
Really Smart People learn from
other people's mistakes!
So, if you can't be Really Smart, at least be Smart!
