In CPython, the exception would have been a subclass of Exception, which
defines a __getitem__ method. Index 0 would then contain the error
number and index 1 an textual description. So the httplib will most
likely work on CPython.

OTOH, the java exception is just passed back from the jython socket
module. This exception can not be indexed as a list, therefore we get
the AttributeError: __getitem__. There is also no error number in a java
exception.

I'm not yet sure what the right long term solution is. Either httplib
could test that the exception is a sequence before doing any indexing.
Or the socket module could catch the java.net exception and reraise it
as a SocketException.

The new socket module re-raises Java exceptions as Python exceptions, so
this is fixed.
