It's what I've always used.  It _has_ to set up /etc/alternatives, because
update-java-alternatives is just a front end to update-alternatives, and
update-alternatives is the correct way to modify /etc/alternatives. 
Whether it fixes "java -version" is just a matter of whether you've got
something on the path ahead of the version pointed to by the alternatives
system.
