good guess...
you do a for /r which cause the entire tree of directory to be parsed
if you replace
for /r "%JRUBY_HOME%\lib" %%i in (*.jar) do @call "%~dp0_jrubysetcp" %%i
with
for %%i in ("%JRUBY_HOME%\lib"\*.jar) do @call "%~dp0_jrubysetcp" %%i
in _jrubyvars.bat
it works as expected...
I will file a bug and provide my 2c solution.
