Solution:

To solve this we need to patch the jython-modules.jar. For default JDeveloper installation path we need to go to C:\Oracle\Middleware\wlserver_10.3\common\wlst\modules and extract the jython-modules.jar using a utility like 7-zip. Then we need to open the javashell.py python script inside lib folder and add at line 139 a String for Windows 8 OS:

_osTypeMap = (
        ( "nt", ( 'nt', 'Windows NT', 'Windows NT 4.0', 'WindowsNT',
                  'Windows 2000', 'Windows 2003', 'Windows XP', 'Windows CE',
                  'Windows Vista', 'Windows Server 2008', 'Windows 7', 'Windows 8' )),
        ( "dos", ( 'dos', 'Windows 95', 'Windows 98', 'Windows ME' )),
        ( "mac", ( 'mac', 'MacOS', 'Darwin' )),
        ( "None", ( 'None', )),
        )
