Resolved putting JMS Message through JMS Listener interface
Resolved in Pega Version 8.2.7
When using MS Listener integrated into Pega running on WebSphere Liberty, the listener was running correctly and able to consume JMS Messages. The JMS Listener ruleform provided options to browse and put JMS messages. However, when attempting to put a message into the destination queue, an error occurred. Investigation showed that if the resource lookup was using 'Resource references' on JMS Listener, the naming context was initialized with a null hashtable. This has been corrected by modifying AddJMSMessage and GenericViewJMSMessage to initialize the naming context with the default constructor RefreshJMSMessages to set JNDIServerName and pass the current parameter page when calling GenericViewJMSMessage.

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.

QP exception handling improved
Resolved in Pega Version 8.2.7
There is currently a configurable maximum size limit for QP items of 5MB. If the message size exceeded 5 MB, the message failed to be enqueued to Kafka, but still ended up in the delayed message table where it remained. This caused issues with pzDelayedQueueProcessorSchedule JS as a result. To resolve this, the system has been updated to better detect Kafka errors related with message size and move any corrupted item to the broken message queue with the appropriate message attached.

Alerting features added for Listeners
Resolved in Pega Version 8.2.7
An enhancement has been added for Email Listener alerts. At the end of each listener's processing cycle, the system will determine the average processing time per message, the total processing time of the listener, the total unread messages count, and total number of messages processed. In each AESRemote agent run, this data will be published to the PDC, where it will be analyzed and any necessary alerts raised.

Handling added for reactivating combined Passivation and AccessGroup timeout
Resolved in Pega Version 8.6.2
Refreshing a passivated browser window in Dev Studio for an operator with a combined access group and passivation timeout was resulting in a blank screen after re-authenticating. InvalidParameterException and InvalidReferenceException messages were logged. Research showed this was caused by a missing pxPortal property on the pxThread page along with missing Application and Accessgroup pages. While refreshing the browser along with the top URL, there will be few requests with tab threads calling activities such as deletedocumentpg and SetProcessWindowName because there was an unload. Because these requests reached the server before re-authentication, the threads proceeded to the activation flow, causing properties such as pxPortal, Application, and Accessgroup pages to be removed from the thread page and requestor page according to the condition that the requestor was not yet authenticated. To resolve this, the logic in session.internal.authorization.context.BasicApplicationContextImmutableImpl#applyApplicationProperties has been updated to skip removing application page properties from the thread page in this combined Passivation and AccessGroup timeout scenario.

Java Bean import updated to handling differences in Java 7 and Java 8
Resolved in Pega Version 8.6.2
The behavior of the java bean Introspector class is inconsistent across different versions of the JDK when detecting indexed properties built off of java.util.List objects, causing Java Bean import to generate differently in Java 7 and Java 8. This has been resolved by updating PRIndexedPropertyDescriptor to better handle this JDK difference by resolving indexed read and write methods manually using simple reflection.

Java object type removed from pyStream to resolve GetFile class error
Resolved in Pega Version 8.6.2
It was not possible to perform Property-Set on pyStream(java.io.InputStream) to assign it with another object of type(returned by pxGetFile Rule-Utility-Function). This was caused by a strongly typed java.io.stream in the pyStream property creating conflict at runtime with S3WrapperInputStream from the D_GetNewFile call, and has been fixed by removing the java object type from pyStream.

Documentation updated for accents and special characters used in search
Resolved in Pega Version 8.6.2
The "Pega search API" article has been updated to reflect that the search functionality in Pega Platform does not match accented words with unaccented. For example, searching for santé and sante will retrieve different results. In addition, Domain Specific Language (DSL) includes special characters for use when searching, for example '-', '_', '!', '@'. However, the system retrieves various results depending on the way the special characters are used in the search query. If the query contains special characters that are not escaped, the system may retrieve incorrect results. For example, not escaping the slash mark in the 25/02 query may cause the system to ignore the special character.

Handling updated for queue processor locks
Resolved in Pega Version 8.6.2
The Final activity mentioned in the processing epilog of the Service File rule was not being consistently called from File Listener, causing some of the cases to become stuck and not continue to the next stage. Investigation showed that if the lock was held by the queue processor requestor, the system was unable to obtain the lock but still proceeded to update the LogServiceFile page and persist it. This resulted in overwriting changes made on the LogServiceFile page by the requestor, resetting the completed-batches-count set back to 0. To resolve this, RuleServiceFile -> updateLSFBatchCounts() will call the overloaded lockAndLoad() method in LogServiceFile that accepts a parameter called lockAttempts. This will attempt to obtain a lock for a given number of times before throwing an exception.

Updates have been made to improve security around unprivileged users and unregistered requests.
