Changelog cleanup added for de-optimized properties
Resolved in Pega Version 8.4.4
Unwanted optimization was automatically added to properties for the Application-Work-Casetype class created using the wizard in the App Studio. Attempts to remove the optimization did not work: the property advance tab was showing the optimized classes details even after deleting and recreating the property. When a property is optimized the system adds entries to pr_changelog for the list of classes it has optimized. When the property was deleted, the pr_changelog was not cleared. This was a missed usecase, and has been resolved by overriding the Cleanup activity at Rule-Obj-Property class to delete the pr_changelog entry associated with that if it is present.

Initialized entryName for light weight inventory instance
Resolved in Pega Version 8.4.4
When running deployment on a new pipeline created for the next minor version, once the deployment process got to the point of showing aged updates, the “view aged updates” came back as blank screen. Viewing the logs showed the aged update elements come back but were missing the pyName associated with them. Investigation showed that the system did not have support for setting the mEntryName for LightweightInventoryInstance objects. This has been resolved by adding a junit to ensure that getEntryName() doesn't return as null and should be equal to pzInsKey.

Hot Fix Manager updated to use installation order for schema import
Resolved in Pega Version 8.4.4
Schema changes were not being imported during the hot fix manager DL import process. Investigation showed this was due to hotfixes in the DL being iterated over from newest to oldest, causing older hotfixes to replace the value added to a map by the newer. To resolve this, the system has been updated to use hotfix install order, which considers selected and dependent hotfixes, rather than ordering newest to oldest. This ensures that newer table representations will override older rather than the other way around.

Web Tier busy threads released on timeout
Resolved in Pega Version 8.5.4
Tomcat Web Tier Busy Threads were not being correctly released, causing stability and performance problems that included health check pings not receiving a thread to service the request so the node was marked as bad, users were quiesced, and the node replaced. Investigation showed the 'put' on the blocking queue did not time out when the queue was full and waited indefinitely, keeping the thread blocked. To resolve this, the system will use 'offer' on the blocking queue instead of 'put' to force thread release on timeout. In addition, debug logs have been added to understand when the offer (or Put) does not succeed and the state of the queue that is causing this issue; the debug logs for class com.pega.pegarules.session.internal.serverpush.RoboticAutomationImpl should be enabled only if the thread busy issue is observed and for limited time window while actively debugging.

Resolved Push Node Daily Information exception
Resolved in Pega Version 8.5.4
The "Push Nodes Info Daily" agent was generating an exception on each of the nodes. This has been resolved by enhancing the PegaAESRemote code to handle the exception and get the node info locally, then push it to the console when it is not able to get it via the cluster management API.

Certificate match will use Subject Distinguished Name
Resolved in Pega Version 8.5.4
Signature verification was failing due to the system not finding the matching root certificate for the chain. The root certificate was in the trust store, but the system found a different certificate first and that other certificate (an intermediate certificate) was not considered a valid certificate for validating the whole certificate chain. This was traced to filtering on the Issuer Distinguished Name (DN) instead of the Subject DN and was due to intermediate certificates potentially having the same Issuer as a root certificate (e.g. if that root certificate was used to create the intermediate certificate). To resolve this, an update has been made to check the Subject DN instead of Issuer DN.
