Hotfix hashmap cleanup improved
Resolved in Pega Version 8.1.7
A DL installation failed with an out-of-memory error. It was observed that many CacheEntry(VersionedJdbcJarRwader.java) hashmaps were being created to store the details for each hotfix but that were then never cleared. This has been resolved by adding the finally block in CodeImportProcessImpl.java class to call the shutdown method for proper cleanup. In addition, the default command line utility (prpcUtils) has been updated to use JVM settings of Xmx 4GB and capture a heap dump if an out-of-memory error is encountered. The auto-generated prconfig.xml has also been updated to leverage its minimal startup setting which will avoid loading the conclusion cache into memory.

DeleteDocumentPg added to allow list
Resolved in Pega Version 8.7
During performance testing with CSRF settings enabled, a '403 Forbidden' error was seen in the network trace when FinishAssignment called pyActivity=pyDeleteDocument on close action. This has been resolved by adding pyDeleteDocumentPg to the list of allowed activities.

Installer files updated with class loader conflict resolution assistance
Resolved in Pega Version 8.1.7
When sending emails with attachments, errors were observed relating to a loader constraint violation indicating that when resolving interface method, the class loader of the current class and the class loader for the method's defining class had different Class objects for the type used in the signature. The resolution for this requires user configuration of the app server, and the following files for the install guide have been updated with the appropriate information:Deployment-guides-dita/install.ditamap Deployment-guides-dita/Content/Topics/app-server-config/creating-jdbc-driver-module-jboss-tsk.dita Deployment-guides-dita/Content/Topics/app-server-config/delegating-javax-activation-to-JRE-loader-tsk.dita

Corrected requestor status flag for direct map
Resolved in Pega Version 8.1.7
Numerous "Unable to create requestor" alerts were logged. This was traced to an error in HttpAPI where after retrieving the requestor from the internal requestor map directly, the requestor creation status flag was not set properly. This caused last action to post that alert instead of the correct notice of "existing requestor retrieved". This has been resolved so the flag reflects the correct status.

Local UUID cache will be updated when merge event is detected
Resolved in Pega Version 8.1.7
Cluster-related issues were seen in multiple production clusters. For some nodes in the cluster the Cluster Management screen showed all expected nodes with valid Node IDs displayed, and on other nodes the Cluster Management screen showed the node ID of itself, SERVER@localhost:5701. On an impacted node displaying the wrong ID, the Node Information landing page did not work and displayed the error "Unable to execute job on ." Multiple advanced agents running on nodes in the affected clusters, both with correct and incorrect IDs, also failed with a similar error "Unable to execute job on <node's job id>". This was traced to a merge performed after a split brain. To resolve this, the code has been updated to handle merge events: when the node UUID is changed as part of a split brain recovery, the local UUID cache will be updated when the merge event is detected.

Improved upgrade handling for tables using classes with property references
Resolved in Pega Version 8.1.7
After upgrade, some page property values were blank and exposed database columns did not contain the values. Investigation showed that the reference properties did not have context and hence column population was not able to determine their value. To resolve this, instead of doing column population for all the columns, the system will identify classes that have property references and that are being optimized as part of upgrade process and maintain a list of specific columns to update.

Enhancement added to modify URL encryption for load testing
Resolved in Pega Version 8.1.7
An enhancement has been added which allows conditionally modifying URL encryption for load testing. This uses the flag crypto/useportablecipherforurlencryption: if true, a portable hardcoded key is used to encrypt the URLs and if false, a dynamically generated key per thread/requestor is used to encrypt the URL.

Column population honors thread count of 1
Resolved in Pega Version 8.1.7
The thread count parameter in the column population activity was not being honored, causing repeated deadlocks when trying to populate columns. Investigation showed that the ExposeCols process did not honor the thread count when it was 1 (the default is 4), and this has been fixed by adding the necessary code so that if the thread count is 1, it will not run in multhreaded mode.

Documentation updated to clarify displaying property values for Declare Expressions
Resolved in Pega Version 8.7
The documentation regarding Declare Expressions rules has been updated to clarify that declare expressions do not support displaying values of target properties in the user interface if the target property is an embedded property and if the calculation engages forward chaining. Declare expressions always display property values if the calculation uses backward chaining. During forward chaining, the system might render the UI before populating the clipboard, and the properties are not visible in the UI. To show updated values, define refresh conditions in the UI to get new values from the server when the values change.
