errors while trying to run jython3

[sohail288]

Here's what I'm getting

$ ./dist/bin/jython -vvv

I compiled it successfully after the following modifications

Anyone know what's going on? Or how to go about debugging it?

My machine.

Intel Core I5 2.5 GHZ, 16 GB Memory, running on OS X 10.9.5

Tried to debug it and narrowed it down to line 1747 in Py.Java

                imp.load("site");

Here is the manual exception message that I print in the try-catch block of that load call.

@sohail288 Thanks for reporting, I'll try on my OSX machine.

I believe this is fixed here: https://github.com/jython/jython3/commit/0d924492ec58c8c1706d73dbeef5064c585c1239
