Java, Ant and Eclipse in ac-ready

[Jacek Konieczny]

Hello,

Last week I have prepared a bunch of Java packages and sent them to
ac-ready. The packages include:

- Sun JDK/JRE
- fully built Ant (without --with bootstrap)
- Eclipse

And, of course, all dependencies.

Most of those packages are available only on ix86 (x>=5) and AMD64 (Sun
JDK availability limitation). 

I hope I developed some kind of best-practices for packaging Java stuff
in PLD, and made the important first step to enable Java in Ac.

Please test the packages from ac-ready and if they work, then they may
be moved to ac-main.

Greets,
        Jacek
