I believe nose works on Jython 2.5 (an alpha of 2.5 can be downloaded
here: http://downloads.sourceforge.net/jython/jython_installer-2.5a1.jar

Or you could build from svn:

https://jython.svn.sourceforge.net/svnroot/jython/branches/asm

By a non-standard install process?

Trying to do a normal install gives:

~/work/nose/nose-0.10.3 $ jython setup.py  install

Looks like sys.executable is None?

I haven't had much time to dig ...

Sorry, sys.executable isn't being set properly with the current launcher 
script (which is actually not a launcher script bug, it's a Jython bug).

For the next release the launcher script has been rewritten and 
hopefully at some point we'll also fix the Jython bug that causes system 
properties not to be read.

The basic sticking point is we have so many ways to specify Jython 
options - properties, -D, the registry, command-line flags and 
environment variables - but which ones take precedence isn't documented, 
consistent or tested.  This needs to be fixed, and I'd be happy to do it 
if we can figure out what the precedence should be.

There's a workaround to set sys.executable in the comments for issue 
1069:
