>Can anyone else confirm this experience?
Yep, Yosemite dropped Java 6. Definitely an annoying extra barrier for
developers. But there's a FAQ entry
>When replying to a post like this, is it the done thing to reply to the
list in general or should I be replying just to the original poster?
You did the right thing - reply to the whole list. That way there is a
complete record of any discussion-especially important on a general topic
like this. Personally, if I ever get a private mail in response to
something, I cc the list in my reply (see also:
Out of curiosity, how do people feel about establishing set guidelines for
when to advance Java versions (e.g. if it's 18 months past the end-of-life
release and under 2% of the users would be affected, just upgrade)? There
will certainly be times when this question will come up again... and my
only hesitation towards agreeing with consensus here is that these
particular mailing lists seem likely to be biased towards active developers
(who I would expect to prefer newer Java versions).
P.S. Thanks for starting this thread Tobias!
