I think that you should drop eclipse and netbeans instead of Sun's JDK, if you do not have enough manpower.
Eclipse and netbeans are mostly useless as deb packages. It is more convenient to download it manually and install in your home directory. Both eclipse and netbeans have their own update and plugin installation subsystems.
On the other hand JDK, to some extent, integrates with operating system. For example with alternatives (there are more links than just java and javac in alternatives for JDK). It was very convenient to have official Sun's JDK automatically installed and updated.
I think, that Sun's JDK is very widely used in serious java software development. OpenjJDK is not yet an option for production systems.
