@copilot please add logging to the toAdmin/fromAdmin/toApp/fromApp methods in the ApplicationAdapter in the test implementation.

@copilot please add logging to the toAdmin/fromAdmin/toApp/fromApp methods in the ApplicationAdapter in the test implementation.

Done in commit 2d30768. Both AcceptorApplication and TestConnectorApplication now have their own Logger and log all four callbacks (toAdmin, fromAdmin, toApp, fromApp) at INFO level with the session ID and message.

@copilot I cannot see any session-related events being logged in the test. Please pass a LogFactory to the Session.

Done in commit 68bbb0f. Replaced SLF4JLogFactory(new SessionSettings()) with ScreenLogFactory(settings) in both createAcceptor and createInitiator. ScreenLogFactory writes directly to System.out, so all session-level events (incoming/outgoing messages, state changes) are now visible in the test output.

@copilot change test as follows:

• add a heartbeat interval of 5 seconds
• do not disconnect the session before receiving a heartbeat
• check that the logout message does not contain a "too low" message

Done in commit fb0c0d5. Changes made:

• HeartBtInt=5 set on both acceptor and initiator.
• Heartbeat wait: TestConnectorApplication.fromAdmin now counts down a latch when a Heartbeat arrives that does not have PossDupFlag=Y (i.e. it is a freshly generated heartbeat, not a replayed one). The test waits up to 15 seconds for this before stopping the sessions.
• Logout check: TestConnectorApplication.toAdmin collects all outgoing Logout messages. After the graceful shutdown (post-finally), the test asserts that none of the captured logouts have a Text field containing "too low" — which is the text doTargetTooLow places in the Logout it generates when the buggy SequenceReset arrives.
