Per this homebrew bug:

...this line in the launcher shell script fail with syntax errors from expr:

    if expr "$link" : '/' > /dev/null; then

Modifying the line to read as follows fixes the problem.

    if expr "$link" : '\/' > /dev/null; then

I have not been able to verify that this fix doesn't cause problems on other operating systems.

Confirming same bug also exists in Jython 2.7a2 under Mac OS X 10.8.2 "Mountain Lion). The suggested change appears to fix this:

$ jython
expr: syntax error
Jython 2.7a2 (default:9c148a201233, May 24 2012, 15:49:00) 
[Java HotSpot(TM) 64-Bit Server VM (Apple Inc.)] on java1.6.0_37
Type "help", "copyright", "credits" or "license" for more information.
>>> quit()


$ jython
Jython 2.7a2 (default:9c148a201233, May 24 2012, 15:49:00) 
[Java HotSpot(TM) 64-Bit Server VM (Apple Inc.)] on java1.6.0_37

Oti, any opinion on this?

Still present in bin/jython - need to revisit

I would assume this backslashing is safe in general, but we would have to test to verify this assumption.

On a side note: on Mavericks, there is no issue with the Jython launch script. So if this is a Mountain Lion only issue, it's going to be tough for us to test.

Bug #2076 (a duplicate) has a proposed fix

No longer be an issue for Jython 2.7, which uses a CPython 2.7-based launcher, if that version is installed. But that's the case on OS X 10.8 or newer.

Will not fix for 2.5
