So what? You've noticed that changing one binary managed by the
alternatives system doesn't affect other (different) binaries managed by
the alternatives system. Doesn't seem surprising to me.

If you want /usr/bin/javac to point to the javac from the Sun JDK, do
something similar to what you did wrt /usr/bin/java:
sudo update-alternatives --config javac
And while you're at it, do the same for appletviewer, javadoc, javah,
jar, jarsigner, javaws, jconsole, ...
Or simply uninstall OpenJDK if you're not going to use it anyway.
Or prepend your path with the bin directory of your preferred Java
installation.

Or - maybe the least painful way to change the all Java alternatives -
take a look at update-java-alternatives.
