Appeal for updating the java page

[Kamil Choudhury]

I recently went through the same ordeal. 

The deal here is that you have to have a JVM already installed on your system 
in order to install OpenJDK. Effectively, then, the installation of java/openjdk6 is a 
two step process: first you install the java/diablo-jdk16 port by downloading and 
installing the relevant package from freebsdfoundation.org, and then you subsequently 
install java/openjdk6. 

Afterwards, obviously, you have to change your PATH variable so that you invoke 
the newer openjdk6 by default. 

I could have sworn that java/openjdk6 tells you this when you try to build the port
though.

Agree that there could be more thorough documentation around this.
