Locking added to avoid null pointer error for auto-populate property
Resolved in Pega Version 8.3.6
After configuring the auto populate property "OrgProduct" which referred to a data page, the system experiencing heavy load led to the property not getting properly initialized. This resulted in a WrongModeException and NullPointerException. To resolve this, the system has been updated to lock the requestor when Queue Processors execute their activity. This will prevent race conditions and concurrent modifications if other threads are accessing the same requestor.

Data Page Save correct in batch mode
Resolved in Pega Version 8.3.6
After configuring a List type savable Data Page with save activity in Code-Pega-List, the save data page was triggered from utility of flow from the queue processor to handle queueing 10k data items and creating 10k work objects. When this was run, a field dpClassName was being changed by different threads in DataPageSaverImpl.java. This has been resolved by making the class DataPageSaverImpl.java stateless to ensure thread safety.

Logging for MultiNodeSynchronize lock attempts changed from error to warn
Resolved in Pega Version 8.3.6
The File Listener was logging numerous errors stating "Unable to establish MultiNodeSynchronize lock while trying to determine if listener is enabled for this node". Handling has been previously established for error cases when the Listener is unable to establish a MultiNodeSynchronize lock, but this condition continued to be logged as an error even though it was not related to any failures in functionality. To resolve the logging issue, the logger level has been changed from ERROR to WARN.

In order to improve accessibility, aria-hidden has been added to button and link controls for decorative images, and the alt attribute will be generated by the icon control only when the icon source is Image. The icon control has also been updated to set accessibility roles based the following:if actions are configured -> role=button if no actions are configured -> role=img if type is url/phone/email -> role=link

Traffic handling added for offline pod condition
Resolved in Pega Version 8.3.6
If one of the pods in a cluster went down and failed to restart by itself due to Hazelcast Cluster rejoining issues, there were intermittent issues of non-availability of the system. Investigation showed this was due to traffic being routed to the broken pod because the health check returned a false positive. This has been resolved by adding an update to return failed status when the exception "java.lang.IllegalStateException: Cluster has not started or is not fully initialized." is encountered.

ML model continue tag error changed to debug logging
Resolved in Pega Version 8.3.6
Log entries were seen indicating "The continue tag is found without a start tag for window Line1 1234567890 in text". This appeared to be coming from the MLCommand java class. Investigation showed this occurred when the ML model believed a portion of the text (token) was a continuation of the entity because it has not found the starting part of the entity. This situation is not currently treated as a valid output, so an update has been made to change the logging level from error to debug for this case.

Duplicate key exception resolved for adaptive model
Resolved in Pega Version 8.3.6
During the model snapshot update, a DuplicateKeyException was generated while trying to insert a record in to the predictor table. This did not affect the model's learning, but did appear ion the model monitoring report. This was traced to a local scenario of having the same outcome values defined on the model with different cases (Accept and accept). All predictors used in an Adaptive model are inserted into the model monitoring tables as a part of the monitoring job: because the monitoring tables are not case sensitive, this lead to a unique constraint exception since there were multiple IH predictors with the same name. To resolve this, validation has been added which will skip adding duplicates from new responses.
