Healthcheck will only initialize after successful node startup
Resolved in Pega Version 8.5.2
Nodes were not starting up, but because the Healthcheck service was initialized even though the node was not started properly, errors related to that were overriding the actual exception causing the node startup to fail and it was not possible to diagnose the startup issue. To resolve this, an update has been made that will ensure the Healthcheck service is only initialized when the node is initialized successfully.

Updated JSON DT nested page property handling
Resolved in Pega Version 8.5.2
In a JSON data transform, when using an "Update page" step on a single-page property, as a child step of an "Append and map to" step where a pagelist property is given, the pagelist was populated with only one result but the single-page property was treated like a pagelist and received multiple results. This has been resolved by updating the ClipboardJSONDeserializer implementation and downstream abstractions to support "clipboard only" relations as properties in nested PageLists.

File Listener made more resilient
Resolved in Pega Version 8.5.2
When file listener encountered a FileNotFoundException as a consequence of sporadic AmazonS3Exceptions, the listener was disabled and no retries were made. In order to make the file listener more resilient, FileMatchConcentrator has been updated. While file listener is running and trying to get the next set of files, if the isDirectory() method returns false due to a non-existent directory or some other intermittent issues, instead of throwing an exception and shutting down the file listener, the system will now log the exception and continue.

Email listener update for Microsoft Exchange server
Resolved in Pega Version 8.5.2
After upgrade, TooManyObjectsOpenedException/MapiExceptionSessionLimit errors were seen when starting the email listener. Investigation showed that when the listener was started, two sessions were getting opened and then not closed properly. This was a method originally intended to allow the system to re-use the session to minimize performance overhead, but it is not well-suited for use with Microsoft Exchange server as the Exchange server is unable to cleanup idle sessions. As a result, too many MAPI sessions were opened and led to an authentication exception while opening additional sessions. To resolve this, an update has been made so the system will close the session while the listener sleeps. This stop, restart and graceful shutdown scenario for single threaded email listener scenarios will create a new session every time and close it properly.

Warning added to indicate if QP/JS have been disabled via DASS
Resolved in Pega Version 8.5.2
Search was not working, and the error “The Flow Action pre-processing activity pzLPSearchManagerMainActivityWrapper failed: java.lang.NullPointerException” appeared in the search landing page. Investigation showed that the environment was configured with disabled BackgroundProcessing, which prevented the QueueProcessor framework from working. There was no notice in the UI of this condition. This has been resolved by adding a warning that will appear if background processing is disabled.

Email Listener auto-reply evaluation updated
Resolved in Pega Version 8.5.2
Email Listener auto-reply evaluation updatedAfter upgrade, messages were being read but not getting processed for a specific Email listener (RCEmailListerner). The error "Email flagged as an autoreply email and will not be processed" appeared in the logs. Previously, an email was not considered to be an auto-reply only when the 'auto-submitted' header didn't exist or existed with value 'no'. This caused issues with auto-forward or auto-redirect emails where 'auto-submitted:auto-generated' could be in the header. Due to this, email was marked as auto-reply and email listener stopped processing it. To resolve this, the system has been modified to mark the message as auto-reply if it finds 'auto-submitted: auto-replied' in the header, but not 'auto-submitted:auto-generated'.

Adjusted email listener behavior for authentication failures
Resolved in Pega Version 8.5.2
After upgrade, email listeners were not staying up during connection outages. This was traced to the handling of authentication failures when trying to reconnect, and has been resolved by changing the disconnected listener state to sleeping and raising an alert for authentication failures.
