Description Albert Cardona 2011-02-14 23:36:54 CST 
Running a python script in MacOSX results in the error pasted below.
The line in question is the line at Jython_Interpreter.java:116 that I changed recently and that allows for the PythonInterpreter to return the value of the evaluated code. Apparently that doesn't work in a MacOSX.

Comment 1 Johannes Schindelin 2011-03-23 15:11:43 CDT 
That's fixed now, correct?
Comment 2 Johannes Schindelin 2011-04-27 17:39:16 CDT 
I assume that's a "yes".
