Re: [e4-dev] JDK level for e4 work?
|
I agree with Ed.
As a practical matter, I'm inclined to view Dalvik (Google's Android VM based upon Java 5) as the only viable embedded Java VM going forward--even though saying so likely won't make me popular with a few other folk. That's not what I want, but it's what seems to be happening.

Kevin,
Not that it's entirely a relevant question, but will the embedded space
ever more forward again? At Eclipse we'd argue: if the community cared
enough, they'd produce a Foundation 1.2 for Java 5.0. It can't be that
hard, but I suppose Sun leaves the community in a straight jacket.
This seems an ideal approach for making Java go extinct in the embedded
space. Basing an important design decision around this terribly sad
story, seems terribly sad. And of course the target is likely to move
by the time the arrow comes close...
You recall there was talk about cross compiling 5.0 code to 1.4? There
is a "secret flag" already, but I think that goes against the rules as
well. I'm not sure the purpose for such rules. It seems all very
wrong...
Regards,
Ed

Hi all,
I'm a little confused about what JDK level we said we'd use for e4
work.
In the former e4-incubator mail list
[1] we said, "We'll discuss at the summit". In the summit
notes I see lots of discussion [2] but no conclusion. I was not in
that session, so perhaps there was a conclusion that I missed/was
missed
in the notes?
In doing the recent CSS work I set
the
dependency as JDK1.5 because that's what I saw in the following
projects:
org.eclipse.e4.ui.services
org.eclipse.e4.ui.workbench
Many would like 1.5 for various
reasons
(myself included), but as in the email below, those in the embedded
space
would naturally like something more like Foundation 1.1.
We need a definitive answer to avoid
costly reworking of code to a lower JDK level.
Regards,
Kevin

I have been trying to get the existing code
working with the eRCP
runtime. The good news is after a few hours of hacking and commenting
I was able to get it working. I am now wondering what are the platform
targets for the CSS engine. We can possibly help with the existing
code base to complete it and make it compatible with CDC FP 1.1
(better yet CLCD 1.1 ) also add eSWT and eJface support. Are those
things in the interest and target of the css related work?
