Subject Re: Google Summer of Code 2009

Sian, Jummy,
Some of our recent projects on the Wiki page may put help of an
English speaker to a good use. What do you think?

>>>>    This, I believe, is a Win-Win project, help the Harmony project to
>>>> be localized, as well as help student to train their skill, thus
>>>> sounds acceptable for GSoC. If some other project will use it, that'll
>>>> be a plus.
>>>> 2. the new feature of Apache Harmony project
>>>> a. the requirement of the smallest jre,
>>>>     Yes I see FreeCiv - an amazing project. However as we see, not
>>>> all project get to know if the jre can be customized, and not all
>>>> customer know how to customize the jre. It may be an amazing tool for
>>>> Harmony than Sun, help the customers to make up his smallest jre
>>>> according his own project, which help them to make their program
>>>> download size to be smallest. Do you think it'll be a nice feature for
>>>> Harmony to our customers?
>>>> b. the OSGi/updater
>>>>     OSGi is hot and Apache Harmony has already make its modules
>>>> bundle. I've heard of many java developers believe if the jdk can
>>>> adopt OSGi is helpful. It will help some project to be OSGi without
>>>> apply OSGi module on their projects. And what's more, yes I've got a
>>>> little investigation on this topic as well, it seems Apache Felix can
>>>> be applied on Harmony with a few lines changed and a few new methods
>>>> enhanced on vm, and then start well, And eclipse Equinox looks
>>>> adaptable as well. If we can go a little further, it may make the
>>>> Harmony Project to be the first OSGi-ed JDK on the world - cool and
>>>> attractive to the potential customers, isn't it? If so we can apply a
>>>> update mechanism for Harmony easily.
>>>>     Yes I see the new features are beyond the Spec, I think it's OK
>>>> if we want to excel Sun's implementation and attract more customers.
>>>> Do you think the motivation is acceptable? Is there any technical

>>>>> Hello Jimmy,
