I guess I didn't phrase my question very well, as we are testing the
Java update as well. I wrote a little perl script so I could identify
all of the installed JREs on my servers. Any time we do patches or
updates, I always worry that we've overlooked something small but
critical that will break things in a major way. I tend to follow the
philosophy that if it ain't broke, don't fix it.
I wonder why Sun gave Java the ability to do DST rather than using the
functionality of the underlying OS.
