>             Project: Derby
>          Issue Type: Bug
>          Components: JDBC
>    Affects Versions: 10.3.1.4

> The attached program demonstrates the problem.  Using the ClientConnectionPoolDataSource40 with a connectionEventListener the defined method connectionErrorOccurred is not executed after the Network Server is shutdown and activity is performed on a previously established pooled connection.
> Program also demonstrates that the connectionClosed method is executed when the connection is closed.
> To run the reproduction:
> 1) start network server (listening on default host/port and  -noSecurityManager specified)
> 2) run the program
> Output is:
>  > java DerbyNotification2
> 10.3.1.5 - (579866)
> Apache Derby
