Is it possible to build sun-jdk-1.5 from the source?

[Daniel Tourde]

Hello,

Is it possible to build sun-jdk-1.5 from the source code?
If yes, how to do that?

To be honest, I would like to avoid to install a binary that requires Linux 
support packages. It's not that I do not like Linux (I have 3 Gentoo Linux at 
my disposal), it's simply that my machine is a FreeBSD machine and I would 
like to keep it as simple as possible.
