   os.name is defined as:

   The following names have currently been registered: 'posix', 'nt', 'java'.

   In my understanding, the value 'java' is for the benefit of jython, which is rather poorly. Other third-party implementations which may or may not have a "full os module" (e.g. ironpython) do not -- as far as I can tell -- get to be registered against this value, and Python 3.3's addition of sys.implementation seems like a more reliable (and better supported) way to perform implementation-specific checks.

   Therefore I feel os.name == 'java' only exists to confuse readers of the documentation, but doesn't really provide any value, and should be removed.

   PS: "platform.system()" also documents Java as a value which doesn't seem to make that much sense, however it's an open set so probably less of an issue / source of confusion.
