Because of this, for example,  setuptools from bundled ensurepipe module generates unix exec files in bin, instead of exe:
jython -m ensurepip
jython pip install yolk

result: 
bin\yolk file created instead of bin\yolk.exe

reason:
systemtools detects windows platform by checking sys.platform for 'win32', while jython sets it to 'java'.
I was able to fix this by adding (os.name == 'java' and os._name == 'nt') everywhere in setuptools sources.

It is huge dealbreaker for windows users who want to use others work
