Roland, please try doing

jython --print

and report the results here. The failure is in the attempt to launch java with the the appropriate settings to run Jython using the subprocess module. So for example, here's what it reports on my Windows 8.1 VM:

c:\jython2.7rc2>bin\jython.exe --print
"C:\Program Files\Java\jdk1.7.0_55\bin\java" -Xmx512m -Xss1024k -classpath c:\jython2.7rc2\jython.jar -Dpython.home=c:\jython2.7rc2 -Dpython.executabl
e=c:\jython2.7rc2\bin\jython.exe -Dpython.launcher.uname=windows -Dpython.launcher.tty=true org.python.util.jython

Notably i should be able to directly run the above command line from the Windows prompt, and it should work.
