Pooled connections are closed?

[David Van Couvering]

Hi, all.  I'm working on testing the toString() fix for Connections. 
I'm trying to cover all the bases in terms of our various data sources.

In my tests I create a new instance of EmbeddedXADataSource and 
ConnectionPoolDataSource, and then get an XAConnection and a 
PooledConnection.  From each of these I then call getConnection().  I am 
not sure if this is right, but I'm copying existing test code here.

All this works great, except that the first connection I get back from 
getConnection() is always closed.  Does anyone know why this is?  Is 
this expected behavior?

Thanks,
David
