EmbeddedConnectionPoolDataSource40 never calls the ConnectionEventListener calbacks
-----------------------------------------------------------------------------------

                 Key: DERBY-4225
                 URL: https://issues.apache.org/jira/browse/DERBY-4225
             Project: Derby
          Issue Type: Bug
          Components: JDBC
    Affects Versions: 10.5.1.1
         Environment: Solaris
            Reporter: Alan Burlison
            Priority: Blocker


I'm using EmbeddedConnectionPoolDataSource40 to implement a simple connection pool.  A skeleton
of the code looks like this:

----------
class PoolConnectionEventListener implements ConnectionEventListener {
   ...
}
:
EmbeddedConnectionPoolDataSource40 source =  new EmbeddedConnectionPoolDataSource40();
:
connListener = new PoolConnectionEventListener();
:
PooledConnection conn = pconn.getConnection();
conn.addConnectionEventListener(connListener);
----------

This is so I can catch the connectionClosed and connectionErrorOccurred events and recycle
the connections.  In Derby 10.4.2.1 this all works fine, in 10.5.1.1 it doesn't work at all
- the callbacks never get made.  This makes 10.5.1.1 unusable in anything that uses connection
pooling, such as a JDNI context.

I haven't checked ClientConnectionPoolDataSource40, it may have the same problem.
