building jdk1.4 natively on FreeBSD 5.3

[Ganbold]

Hi,

I would like to install jdk1.4 natively on FreeBSD 5.3.
I know there is a way to install jdk1.4 on FreeBSD using linux emulation 
and linux procfs and I installed jdk1.4 before in such way.
Right now I would like to install jdk1.4 natively on FreeBSD 5.3 without 
any linux emulation.
How can I build jdk1.4 natively? Is it possible?
If it is not possible, is there any plan to make native port of jdk1.4 or 
jdk1.5 soon?

thanks in advance,

Ganbold
