Were you aware that getJarFileName() produces a malformed format under windows?
1) It prepends a "/" before the drive-letter
2) It does not use system specific seperator-char
I am going to fix this and hope that there is no code depending on this bug. Also note that using the python-launcher sys.executable is set to "blah\\jython.py", which is fine. But I suspect it would do the same if launched with jython.exe. Scanning the source of jython.py I see nothing to care for this (but maybe I overlooked it).
Unfortunately I could not test this directly using jython.exe, because jython.exe crashes on my system (win 7 64 bit). But that's a separat issue (coming soon).
