I narrowed this down since I could reproduce it. Basically one of the 
classes in the chain isn't public but overrides 
java.sql.Connection.close. That combined with the interfaces having 
their own different close method causes the java.sql.Connection.close to 
not show up

Extract the tar ball and run:
$ jython test.py 
nargs: 1
interface SpecialConnection, false, 0, public abstract void 
SpecialConnection.close(int)
	(int, )
None
Traceback (most recent call last):
  File "test.py", line 4, in <module>
    c.close()
TypeError: close(): expected 1 args; got 0
