Custom header character encoding for Subject added
Resolved in Pega Version 8.5.5
Case correspondence that contained a Subject with accent characters such as "Invitation à être" was being rejected by MailJet on the basis of encoding issues on the "Thread-Topic" when using custom headers. The error "BAD HEADER SECTION, Non-encoded non-ASCII data (and not UTF-8)" was generated. This was traced to the Send Email Smart Shape handling when using custom headers, and has been resolved by encoding the Subject before appending it to the Thread-topic header while adding custom headers.

Java Bean import updated to handling differences in Java 7 and Java 8
Resolved in Pega Version 8.5.5
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.

RemovePrivateBlockedAndWithdrawnRAQs updated to avoid exception
Resolved in Pega Version 8.4.2
If the method removePrivateBlockedAndWithdrawnRAQs() (present on the AgentRuleUtils.java class) had both the "ignore personal rulesets containing checked out files" and "ignore "Blocked or Withdrawn agent" conditions set, raqsItr.remove(); ran twice and resulted in a java.lang.IllegalStateException. This could lead to undesired outcomes such as agents not showing up properly. To correct this, the code has been refactored to avoid running raqsItr.remove(); more than the necessary number of times.

Processed in last hour generated correctly
Resolved in Pega Version 8.4.2
After upgrade, the 'Processed in last hour' for pyFTSIncrementalIndexer (or any other queue processor) did not show the totals processed. This was traced to an error in a declare expression rule, and has been corrected.

Queue processor handling updated
Resolved in Pega Version 8.4.2
After upgrade, the queue processors were not processing all the items in the queue, however the value under the 'number of items processed in the last hour' in the Admin studio showed the value was equal to the total number of items in the queue. This was traced to the an incorrect offset kept by the queue processor in the data table (Data-QueueProcessor-Run-Partition). Because the incoming messages from Kafka have a lower offset than the one kept by the queue processor, messages were treated as duplicates and not processed. This has been resolved by adding a partitions-validation mechanism on QP startup. To assist in proper handling, any messages identified as potentially already processed will be moved to the broken messages queue.

Declaratives disabled during startup
Resolved in Pega Version 8.4.2
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.

Improved timing for node tracing termination
Resolved in Pega Version 8.4.2
The tracer stopped tracing after tracing a certain number of events. This was due to communication timing issues for tracer events from one node to another node in a multi-node cluster environment, caused by the Tracer Client using the pzMaxEvent property which limited the maximum number of events fetched at a time to 200. Any leftover Events should have been fetched in the next request, but when the consuming node's service ended after the 200 events, the system removed the service requester entry from the distributed Map and disabled remote node tracing as part of cleanup of the service execution. To resolve this, an update has been made so the node tracing will not be terminated until the service execution ends and there are no more events to process.

Class Loader cache values wrapped with WeakReference for improved cleanup
Resolved in Pega Version 8.4.2
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.
