Issue1158

$ cat v.py 
from ast import PyCF_ONLY_AST

def parse(expr, filename='<unknown>', mode='exec'):
    return compile(expr, filename, mode, PyCF_ONLY_AST)

a = parse("1/2")
e = compile(a, "<string>", 'exec')
print e


$ jython v.py 
Traceback (most recent call last):

Fixed in r5517

updated in r5518 based on some java integration changes that I just
missed in r5516.

Thanks a lot Frank for fixing this. 

Shouldn't you also commit a test for it?

I did put in a new unit test, though I forgot to check it in with the
original fix.  I remembered a few minutes later -- see r5519 or just
look at the new test_ast_jy.py which contains a single test for this
issue.  Thanks again for reporting it!

Ah, excellent. Thanks a lot for fixing it.

In case you are bored, there is another problem, that we need to get
sympy running on top of jython:

Heh -- I have a couple of things ahead of #1159, but if it is still
there in a day or two I'll definitely take a look.
