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.

Decision table query performance improvements
Resolved in Pega Version 8.3.6
Severe latency was seen after upgrade, and it was not possible to save business rule changes. This was traced to an issue with the decision rule being treated as a custom rule, and has been resolved by inserting a check. In addition, optimization has been added for queries on the pr_sys_decchg table.

Resolved PRQueueLockException
Resolved in Pega Version 8.3.6
A Class Queue not found exception resulted when an SLA was deleted on the same transaction where it was created when deferred save was used. This was an inadvertent side effect of work done on the QueueManager implementation to invalidate previously deferred operations for item and schedule removal, and has been resolved by clearing the processing state for PRQueueLockException when an item reservation fails.

Declaratives disabled during startup
Resolved in Pega Version 8.2.7
Declaratives firing before the engine is fully up can lead to null pointer errors. In order to avoid this condition, declaratives will be disabled during startup so that unnecessary operations can be avoided and system can be started faster.

ArtifactoryStorage URL construction with port updated
Resolved in Pega Version 8.2.7
After configuring a repository as a JFROG artifactory with a ruleform that provided a URL / port number and repository name, test connectivity worked as expected, but deploying the codeset using pipeline or importing the codeset using the import functionality generated the error "Unable to construct artifactory url due to invalid file path". The root cause of the issue was traced to the ArtifactoryStorage java class, which did not accept the port number in the format provided due to changes in the API. If there was no portNumber in the URL, the issue did not occur. To resolve this, the constructor has been changed to properly build the URI per https://docs.oracle.com/javase/8/docs/api/java/net/URI.html.

Class Loader cache values wrapped with WeakReference for improved cleanup
Resolved in Pega Version 8.2.7
Out Of Memory exceptions due to Metaspace were observed on Web tier instances running with a max Metaspace size of 2GB. Investigation showed that in PRClassLoaderDB, mLoaderCache values were wrapped with a SoftReference. To resolve this, the Class Loader cache values will be wrapped with a WeakReference, allowing the cache to free memory when it is no longer needed. JVM options has also been added to switch types of References being used if there is a preference.

Resolved Agile Workbench video recording timeout
Resolved in Pega Version 8.2.7
Using the Record Video option thru Agile Workbench to create an Agile Studio item was either taking an excessively long time to finish or was hanging. Research showed that this scenario could arise when the input parameter value crossed more than 50 characters and triggered the interaction threshold for an alert, and has been resolved by updating the system so that query parameters with size more than 50 are not encoded and added to alert logs.

Added handling for download of attachment with special characters
Resolved in Pega Version 8.2.7
If the name of an uploaded attachment contained a non-ascii character, the upload was successful but the downloaded file had the wrong name without any suffix. This was an issue on WAS or JBoss servers where filenames contained non-ascii characters, and the filename parameter in the content disposition header also contained these characters. To resolve this, the filename parameter in the content disposition header will be encoded as well along with the filename* parameter to handle non-ascii characters in the filename.

Application content storage change corrected
Resolved in Pega Version 8.2.7
Selecting the Content Storage radio buttons set a background property indicating the content storage option was changed, but the property was not actually being set. Investigation showed that the value for pyContentStorageChanged was not being updated correctly before the section refreshed, meaning the selection was never saved. This has been corrected.
