The following code produces an NPE:

from java.lang import Number

exec """
class M(N):
 pass

""" in { 'N': Number}

The source is the following code in PyClass.init:


            if (baseClass != null || interfaces.size() != 0) {
                String proxyName = dict.__finditem__("__module__").toString() +
                                       "$" + __name__;
                proxyClass = MakeProxies.makeProxy(baseClass, interfaces,
                                                   proxyName, __dict__);
            }

namely in this case dict.__finditem__("__module__") returns
null!
