When running jython.bat, this code is expanding a * into a filename, when trying to dequote a parameter:

rem remove quotes around first arg
for %%i in (%1) do set _CMP=%%~i
set _ARGS=%2
goto :EOF

The problem is that the for loop looks for filenames which match the pattern given in %1. With a little script from I was able to fix that problem:

rem remove quotes around first arg
set _CMP=%1
CALL:deQuote _CMP
set _ARGS=%2
goto :EOF



SET _DeQuoteVar=%1
CALL SET _DeQuoteString=%%!_DeQuoteVar!%%
IF [!_DeQuoteString:~0^,1!]==[^"] (
IF [!_DeQuoteString:~-1!]==[^"] (
SET _DeQuoteString=!_DeQuoteString:~1,-1!
SET !_DeQuoteVar!=!_DeQuoteString!
SET _DeQuoteVar=
SET _DeQuoteString=

This might be a dupe of #1356 but I'm not sure

I noticed the same problem too, and because I failed to search the tracker first I submitted #1594 about it. I also found an alternative fix for the problem. 

See also issue #1599 about more problems with special characters in arguments to jython.bat. Having a native .exe launcher for Windows (#1491) would be awesome.

I cannot judge, if the solution proposed here, or in #1594 by Pekka is more appropriate. Apparently, the argument shall be dequoted. Both solutions appear to do the job, although I ask myself, why such a complicated script :DeQuote exists, when the solution is as simple as using the %~ notation :)

I understood this microsoft document so, that the variable substitution is only available in for loops:

Maybe on newer windows versions, it's generally available?

I think the point of :DeQuote is that it handles both single and double quotes. %~1 apparently only removes double quotes but that seems to be exactly what's needed in this case.
