I was able to reproduce this. The oracle Connection object implements 3 
DBAccess interfaces that define their own close methods that take 1 
argument. For some reason the descriptor for close gets confused into 
thinking they are the only available close() methods:

>>> c = 
DriverManager.getConnection('jdbc:oracle:thin:@192.168.21.128:1521:xe', 
'scott', 'tiger')
>>> c.close()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: close(): expected 1 args; got 0
>>> c
oracle.jdbc.driver.T4CConnection@d27a744
>>> T4CConnection = type(c)
>>> T4CConnection.close.printArgs()

Is there some javadoc or something like that online for the Connection 
object in question?  I'd like to make something or the same form as a test 
for Jython to try to fix this.
msg5036 (view) Author: Philip Jenvey (pjenvey) Date: 2009-08-16.00:55:22 
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

Should be fixed in r6676.  Thanks for the report!
