Connection proxying to imitate DissociatableManagedConnection can easily cause
problems
---------------------------------------------------------------------------------------
Key: GERONIMO-4350
URL: https://issues.apache.org/jira/browse/GERONIMO-4350
Project: Geronimo
Issue Type: Bug
Security Level: public (Regular issues)
Components: connector
Affects Versions: 2.1, 2.2
Reporter: David Jencks
Assignee: Dain Sundstrom
Fix For: 2.1.4, 2.2
We have some code to imitate the DissociatableManagedConnection to avoid
connection leaks that proxies connections from the supplied
ManagedConnectionFactory: the proxy implements all the interfaces of the
connection, but not the class itself. However, there's nothing stopping the
ConnectionFactory from casting the (now proxied) connection to the
implementation class it expects.
The TxConnect project at sourceforge illustrates this approach in the
EisConnectionFactory.

One possible solution would be to have a flag to turn on this proxying
behavior. I don't immediately see a way to detect if the problem will occur.
