commons dbcp throws sqlexception when connection is already closed

We recently implemented DBCP in a project and received an sqlexception
from DBCP when closing a connection that was already closed:

java.sql.SQLException: Connection is closed.
 at
org.apache.commons.dbcp.PoolingDataSource$PoolGuardConnectionWrapper.che
ckOpen(PoolingDataSource.java:174)
 at
org.apache.commons.dbcp.PoolingDataSource$PoolGuardConnectionWrapper.clo
se(PoolingDataSource.java:179)

Is this not a violation of contract with the Connection interface?
Snippet from the java.sql.Connection.close() API:

Calling the method close on a Connection object that is already closed
is a no-op.

Granted there was bug in our code, but shouldn't DBCP's
PoolingDataSource abide by the contract specified in the Connection
interface?

I found this Bugzilla bug when looking into this:

I'll try to remember to fix this, since broken links is kind of bad :)
I am not a modeler maintainer (or know much about it for that matter).
If you file an issue, I will be sure to not forget it (prefix with [modeler] and use site somewhere 
in the title (that will trigger my attention..)

Mvgr,
Martin

commons modeler - status?

Posted by brown_k <ke...@air2web.com>.

Commons Modeler folks,

What is the status of this project?    I like the xml format used to 
describe mbeans.

I came across this project via a spring/jmx tutorial 
(http://forum.springframework.org/showthread.php?t=20675).  I attempted 
to modify the Wiki page for Commons Modeler to add this link, but the 
page is locked (http://wiki.apache.org/jakarta-commons/Modeler) and very 
incomplete. 

Also the cvs and download links are broken:
http://jakarta.apache.org/commons/modeler/downloads.html

I'd figure the status would be on the front page rather than on the list 
that gets sent out every once in a while with all the projects and status
