Re: Java 1.3: 10.1 vs. Jaguar

Greg,

Thanks for the rapid feedback.

You might want to do more than hope for portability. I suggest testing the
code under Virtual-PC directly on the Mac as a good step. You can have
more than one JRE installed on virtual Windows, or even more than one
version of Windows on different virtual HD's. And it's SO much easier to
manage than Wintel hardware, dual-boot configs, etc. It may not be as
snappy as real Wintel HW, but sometimes that's useful in testing, because
you can more easily see visual defects in a GUI.

I have found that Virtual-PC runs so slowly as to be useless. The last
time I reinstalled stuff I actually removed my copy. But
fear not--I am not "hoping" for portability, but actually copying
my application to real PC's and watching it do the unexpected.

Mac OS 10.2.1 should be your baseline OS. 10.2.0 had some significant, um,
personality difficulties.

OK.

PB 2.0.1 is markedly different than PB 1.* on 10.1. On the whole, I think
it's an improvement, but it took me some time to get used to it. PB 2 will
convert projects from PB 1's format, but doing so is irrevocable and
in-place, so do a full backup of your projects first.

Of course. But actually I have PB2 on my 10.1.5 OS--it was in an
April 2002 upgrade.

I always worry about backwards compatibility of executables, especially
app-bundles. So it wouldn't hurt to keep a machine or a partition around
with 10.1.x on it, and do trial installs and test-runs of your distros on
it. Or maybe I'm just more paranoid than most.

My understanding, from something I saw on this list a while ago, is that
having multiple 10.x OS's on the same machine has some problems--files
expect to be in a certain place. Is it really feasible to make a backup
of 10.1 onto a different partition and actually run from that if
10.2.1 doesn't behave as hoped?
