Hi Werner,
Thanks a lot for the link.
Regarding the new initiative and the new temporary whiteboard @
GoogleCode... well... please forgive me for what I'm about to write...
.... but I disbelief that things will change in comparison to OFMP or
EFP. I'd like to be wrong ... but I didn't see a single line of code in
SVN; the revision number is still 1; so, nothing happened since March,
when Alexey sent the first message on this topic. The wiki is absolutely
empty, everything else is absolutely empty. This list itself is pretty
silent.
Maybe everyone is waiting for activity before becoming themselves
active? (like me!)
Regarding UOMo... well... this is a pretty tiny subject when we think
about the wide subject of trading systems. Even JQuantLib, which is
considered by many as a large library, can be treated small (or even
tiny) given the very wide subject of trading systems.
I think that collaboration should happen for the benefit of all
participants but we need to have something, maybe a draft or manifesto.
This kind of document is necessary in order to guide people interested
on contributing. Not even a quick document like this can be found in the
wiki hosted at GoogleCode. :(
So, my sad and hard conclusion is that this project does not exist. :(
Again, I'm really sorry for my harsh words but you can be sure that I
will be delighted when someone proves I'm wrong and I will be delighted
when the day comes I commit something to the repository.
Kind Regards
Richard Gomes

Glad to help.
I am not sure, if there's anything going to happen at OFMP, but it is not
directly related to us ar UOMo.
Frederic said, they'll migrate to Eclipse Labs, let's see if that attracts
new committers...?

It is a building block like EMF, most likely to even support it in some way.
If you find a way to use ICU4J (Measure/Currency) in JQuantLib, that'll be
fine, and compatible with both some of Google's projects and Eclipse UOMo or
its extensions towards financial use cases.
The most I'd imagine to see in UOMo itself is probably a more sophisticated
Currency class than ICU4J has and basic currency exchange on top of that.
Probably sets of rules or interfaces to use exchange rates in time and
context, but no concrete implementations. That's up to either you, OFMP or
custom projects.

I will have a look at ICU4J and evaluate how it impacts performance.
IMHO, performance is 'the' critical issue when we talk about financial
applications written in Java. This issue must be considered and
addressed from the day one, every day, otherwise performance will be
poor when compared to C++.
In particular, I believe that enterprise class, low latency financial
applications need RTSJ or something better. GC must be removed from the
equation every time it is possible. Better than trying to solve the
problem of unpredictable performance due to GC, we'd better get rid of
GC whatsoever.
Unfortunately, it's difficult to obtain the best from both worlds at the
same time: (1) elegant programming language and (2) good performance.
