There are some efforts to write an operating system (almost) entirely in Java: JOS, JNode. None of those really took off as a serious operating system.

There have also been attempts at making CPUs that could directly execute Java bytecode as their native instruction set - see Java processor in Wikipedia for a few links. Those also haven't been very succesful.

A Java-based OS is an OS written entirely, or mostly, in Java.

Sun had one too: JavaOS.
 
It is sorta covered in the JavaRanch Style Guide.
