Kevin didn't say to set a /usr/bin/java symlink, he said to set
a /usr/local/java symlink to point to the dir with the jdk/jre
installed, so you can change which dir /usr/local/java points to,
and JAVA_HOME is just set to /usr/local/java so you can update
which jvm/jre things are using w/o having to change the variable
and force ppl to reinit their shells.

a /usr/bin/java symlink doesn't do much for you, as you mentioned.
