Agent restart made more resilient
Resolved in Pega Version 8.4.5
During a timeout outage, agents intermittently encountered a NoClassDefFound error and were disabled. After the database connection was restored, the agents were not automatically restarting. This has been resolved by making the code more resilient to errors; agent will be restarted when a temporary issue is detected, and the restart will be immune to most exceptions.

AES call to mbean disabled
Resolved in Pega Version 8.4.5
Under certain conditions, the AESRemote 'push memory' agent call to the legacy memory management mbean caused unexpected behavior in declarative rules for work running in data flows and queue processors. This has been resolved at this time by overriding the push memory usage agent activity to skip mbean and connect REST.

Corrected race condition that caused JobScheduler error
Resolved in Pega Version 8.4.5
A race condition between the pzInitializeQueueProcessors and pyPersistNodeState job schedulers that both run at platform's start was causing a null pointer exception with the error "com.pega.platform.executor.jobscheduler.scheduler.JobExecutionException: Activity execution failed with [PRRuntimeException]". This has been resolved by moving the QueueProcessor initialization process from JobScheduler to StartupTask.

Improved requestor cleanup
Resolved in Pega Version 8.2.5
Batch- and Browser-type Requestors were building up over time in both the Admin Studio and in the PegaRULES log and not removed until the system was restarted. This has been resolved by adding two extra cleanupRequestor calls to the Email Listener implementation.

Added support for JSON mapping of deep nested pagelist objects
Resolved in Pega Version 8.2.5
An exception occurred when using a JSON data transform in the service activity to map the clipboard data to JSON on the third level of a structure formed as Pagelist-->page-->pagelist. To resolve this, support has been added for nested pagelist mapping with deep nesting of objects (configured for one sided actions) and arrays.

Queue Batch activity correctly passes chlld process access group
Resolved in Pega Version 8.2.5
When users attempted to create an index using the schema tools landing page, an error displayed in the table history stating "Create index failed". Investigation showed that this happened when a user was authenticated without the PegaRULES:DatabaseAdministrator role and then switched to an Access Group with the PegaRULES:DatabaseAdministrator role. The issue was traced to the activity that launched the batch requestor missing the parameter pzUseCurrentAccessGroupForChild due to the Queue Batch activity only passing the default access group authorization. This has been resolved by adding code to pass the additional authorization which will allow users to create an index in this scenario.

Added safeURL encoding for Japanese characters in attached filenames
Resolved in Pega Version 8.2.5
It was not possible to preview a Japanese-titled PDF file attached on a work object. Investigation showed that in case of Japanese characters, file names were not being correctly encoded during the fetch request when JBoss was used. The retrieval worked correctly under Tomcat. In order to ensure consistent encoding, the safeURL API will be used for constructing the URL and for the activities DisplayAttachFile and pzDownloadFromRepository which add the ContentDisposition header.

Check added for lock expiration when using Save for Default locking
Resolved in Pega Version 8.2.5
With the default case locking policy, during the process from creating a Case Object to Submit it was possible for multiple users to edit and save the same work object if the lock expired for the original user. No warnings appeared. To resolve this, handling has been added for a lock expiration scenario: previously, Save for Default locking was not considered. This has now been updated with a check that will evaluate whether or not the lock is gone before attempting to save.

Dynamic System Setting added to Invalidation query to tune performance
Resolved in Pega Version 8.2.5
Running a RuleInvalidation query on an SQLServer database with a large amount of data was causing performance issues. To improve performance, a force order hint has been added which can be enabled with the Dynamic System Setting racache/useForceOrderHintForInvalidationQuery.

WorkPageName preserved during passivation so attachments are correctly tracked
Resolved in Pega Version 8.2.5
When a work object was left open but inactive for a period, using the delete button in the pyAttachFieldRequired section caused the deletion of the Attachment Links for the 500 most recent attachments in the system with the same value for the AttachmentFieldName, regardless of which work object they were attached to. This was due to the delete attachments activity being executed with missing parameters: since data page loading was disabled and read-only data pages are not passivated, the value for the autopopulate property 'WorkPageName' was passed as empty. To resolve this, the data page will be preserved or reloaded as appropriate so the WorkPageName is maintained.
