Hi,
for bug #257381 ("[Discovery] Reduce BREE to Java 1.4") [1] ECF needs a
backport of java.util.concurrent. The Distributed Computing Laboratory
at Emory University [2] provides such a backport and in my local tests
the lib seems to keep its promises.
Is anybody interested in such a backport in Orbit? Does it make sense to
have it in Orbit? If not, I won't go through the hassle of creating an
Orbit-esque version and simple embed it in the ECF consumer bundle.

Even if no one is interested (right now) I'd encourage you to put it in
Orbit anyway ... since it encourages re-use later.
But I agree, it's not critically important to put in Orbit.
How much hassle is it, anyway? Just curious what the "inhibitors" are to
putting things in Orbit.
Too bad the code can't be written to run on Java 5 without the "extra"
plugin and only require the backport if running on Java 4 (or, is that
the plan?).
Thanks,

Hi David,
I don't see a way to write either the bundle or consumers in a way that
it falls back to java.util.concurrency on >= 1.5. If other do, please
speak up. :)
Thus the idea momentarily is to have just one bundle for all >= 1.4
VMs. backports 1.4 is upwards compatibility and will run on any vm >=
1.4 [1]. I've verified this by running the concurrency tests on
different VM versions.
There is a performance penalty though. On VMs >= 1.5 backports-1.4
obviously doesn't exploit newer VM performance features. For the ECF use
case, this is totally acceptable though.
I've created an initial take at ECF's OSU repo [3][4].

How do we continue from here? Can you file a CQ for inclusion in Orbit?

The thing to do is to file a CQ for your own Eclipse Project, then once
that's approved, an "administrative" one is open to put it into Orbit.

Chris Aniszczyk is both a committer on Orbit as well as ECF.

Well, I wouldn't want to take the honor away from Chris :)
I opened the Orbit CQ, but Chris would be the better choice to actually
put it in there and list as technical contact,
since he'll have a long term interest in it.
If he can't for some reason, I'd still be glad to help.

Just so everyone knows, concurrent backport 3.1 has made it into Orbit
[1]. Thanks Chris!

Any plans to make edu.emory.mathcs.backports available in an Orbit build?
