building JDK for new platform

[Robert Pangrazio]

I noticed that to build JDK 6 or higher you need an existing Java
setup. I was wondering how you go about building the JDK for a new
platform. If i have a cross compilation setup for my new platform, can
I use the build machines native JDK, or do I have to have a JDK that
is native to my new platform. If i have to have a native JDK to build
the JDK how do you build the first native JDK?


Thanks
