ConnectionEvent doesn't always fire

[SGI495]

I'm relying on ConnectionListener's ConnectionEvent to start commitment control when an AS400 object connects to the COMMAND service to run a ProgramCall.

This works fine under some circumstances, including when

• the ProgramCall object is passed an AS400 object retrieved from the AS400ConnectionPool without specifying a service, using getSecureConnection(host, user, password)
• retrieving an AS400 object from the AS400ConnectionPool without specifying a service and then calling connectService(AS400.COMMAND) on that AS400 object

However, in some scenarios the event does not get fired, including when

• the ProgramCall object is passed an AS400 object retrieved from the AS400ConnectionPool when specifying a service, using getSecureConnection(host, user, password, AS400.COMMAND)
• calling the fill method on the AS400ConnectionPool object

Because it takes quite some time for the pool to allocate a new job, I would like to pre-fill the connection pool with some connections that are ready to use, but I'm unable to since the ConnectionEvent is not fired and commitment control is not started.

I'm using version 20.0.6.
