Re: uninstalling a jdk/jre



I'd like to use this discussion to throw out a few questions regarding Apple's policy on un-installable preview releases for the JDK.

Assertion: For that policy, I will *never* be installing a DP of *any* Apple JDK because I need the java env to always work.

Questions:

* does the fact that I will never be installing a DP create a chicken/egg situation where Apple won't finally come around to making 1.5 an official platform default due to testing but people like me not testing?

* why does Apple's bundling differ so radically from sun's dist. format (basically everything under a JAVA_HOME) which lends itself to one-off trying of any release version. I don't really accept "end users need to be isolated from JDK versions" as a reason. There's easy ways to maintain that facade without hamstringing developers.

* Apple says "do not install on critical systems". I have one Mac. I'd love to have more, but they cost money. Substantially more money than the wintel boxen that are more typically "lying around". Am I truly in the minority where I don't have spare mac's for one-time DP installations?

any thoughts out there?

If you didn't do a backup, your best choice is to reinstall your OS using the "Archive and Install" option to preserve your accounts and other configuration data.

System software updates typically don't have deinstallers, except in rare
cases.  Developer previews never have deinstallers, in all my years of
experience.  That's why the DP release notes always say you should not
install the preview on a critical machine.

You could search the list archives for keywords like "uninstall" or
"deinstall" for tips on reading the package's BOM and removing Installer
receipts, but you'll still be on your own when it comes to the
effectiveness of such removals.  It might break something in such a way
that you'd have to do a complete OS install anyway, so it would just take
longer to reach the same outcome.

I realize this isn't the answer you were hoping for, but if you look in the
archives, you'll see you aren't the first person to want a deinstaller for
a DP, and the past answers are pretty much what I gave you above.
