This is OK to have these issues, I just want user to be able to setup
their configuration correctly and easily.

Great!

I don't like binaries... we really need to find a way to build from source.

You forgot:
java-config -S icedtea6
emerge --unmerge gcj-jdk

It is not difficult for me or you. It is difficult for regular user
who want open source jdk and doing emerge openoffice for example. The
first jdk will be pulled... If the first jdk is gcj then this will be
installed and used by openoffice. If you want to use icedtea then you
need to complete some more stages. Most users will need some help.

Because it takes space and not needed for many configurations.

I think a simple script in the spirit of crossdev will enable users to
correctly and quickly set up their jdk.
