I maintain a product line that consists of a dedicated Linux system
running Java to provide a GUI interface as a control system for
underlying hardware. I've been working to move to jdk 1.5 (not hard
but I'm busy) and now this new DST thing which is not covered by the
version I've been porting to (1.5.0-b64) makes me want to rething

Older versions of J5 and versions 1.4 and earlier require a simple downloaded
fix from Sun to handle DST.

about going to the latest 1.6. It seems every version change had
problems in the beginning and I didn't even try 1.6 because of that.
Now I'm thinking about it again.

It's hardly the "beginning" for J5 any more.

Bear in mind that J6 is the current release. J5 has been out about two and a
half years, now. J1.4 is the old, creaky, hoary, nearly obsolescent version.

There have been bugs reported in 6, some of which carried over from 5, but for
the most part it works as advertised. Have you been checking Sun's bug list to
see if the issues affect your situation?

Can anyone give me a level of comfort about just going to the latest
jdk and jre? Is there an advantage to going to the latest 1.6 versus
the last 1.5? The liability of 1.6 is, of course, it's not as tested
as the previous releases but, as java has matured, I think that some
of that may be pretty minimal. I don't have enough data to judge.

Ooh, I don't know about all that. Sun's own tests are pretty durned
exhaustive, and 6 has been through quite the beta process. Why don'tcha mosey
on over to their bugs and RFE place if you want to know what issues you might
face?

Perhaps in there you'll find enough data to judge.

In reviewing the bug list (should have done that first) I think 1.6 is
the way to go. I don't see anything that will be negative and a great
deal that will be positive. Thanks for the insight.
