[Jython-users] Strange error message when starting Jython

[Ronald F. <yn...@mm...>]

I have installed Jython 2.5.4rc1 on my Mac. It seems to work fine,
except of one weird error:

When I start Jython by specifying the full pathname, i.e. in my case
~/jy/jython (where jy is a symbolic link to ~/jython2.5.4rc1) everything
works normal.

However, I have also set another symbolic link in my  ~/bin directory,
like this:

ln -s ~/jy/jython ~/bin/jython

since I have bin in my PATH, but not jy. When I now invoke Jython via
this link, I get:

expr: syntax error
Jython 2.5.4rc1 (2.5:723492dbab02, Feb 8 2013, 09:50:55) 
[Java HotSpot(TM) Client VM ("Apple Computer, Inc.")] on java1.5.0_07
Type "help", "copyright", "credits" or "license" for more information.
>>> 

Thus, I again get the Jython prompt, but in addition, I get before a
"syntax error", which I do NOT when I run Jython by typing ~/jy/jython
directly.

It looks to me as if Jython would then try to run some initialization
file, which contains something syntactically invalid. However, I don't
have any *py files in my bin directory.

Any idea where this syntax error comes from?
