Comment #31 on issue 1233 by [email protected]: fix the rest of jython bugs
http://code.google.com/p/sympy/issues/detail?id=1233
Ah, I was looking at the wrong screen. Jython 2.5.2 in SymPy master with
Basic.__slots__ removed gives the NullPointerException. It looks like the
traceback for that and the one from Jython 2.7a2 are very near each other:
Traceback (most recent call last):
