Resolved thread deadlock for rules upgrade process
Resolved in Pega Version 8.2.6
Platform upgrade was getting hung during the rules upgrade process. This was traced to a deadlock related to the conclusion cache entry for a property needing to make a call to declarative cache, where it tried to hold a read-write lock on a resource that was already locked by another thread. This has been resolved by replacing lock with tryLock to avoid deadlock.

Performance improvement for queries on Kafka partitions
Resolved in Pega Version 8.2.6
Even though there were multiple dataflow nodes available in the cluster, all requests were going to single node and causing system slowness. Investigation showed there was a queue processor rule that included the pxPartitionKey attribute which forced all records to be sent to a single partition by Kafka producers. This attribute has been removed.

Handling added for custom authentication in embedded mashup
Resolved in Pega Version 8.4.1
After embedding the Mashup gadget in an external application, at browser refresh a Cross-Origin Read Blocking (CORB) warning appeared and the gadget did not load as expected. A second refresh cleared the error. Investigation showed that when custom authentication is configured, 'use SSL' is checked in Authentication service. That meant that when the user was authenticated, the redirection was not considering the query string entered before authentication and the CORB warning was issued due to a change in response. Because there is special handling for the above use case and post-authentication redirection does not happen through the normal flow (HttpAPI), this issue has been resolved by honoring the query string stored in requestor (entered by user) while redirecting.

Delete Requestor method updated for use with CMT
Resolved in Pega Version 8.4.1
JMS MDB Listeners with Container Managed Transaction (CMT) enabled in Websphere 8.5 had global transactions fail. To initialize a JMS-MDB listener, a requestor of type APP is used. Upon the service being fully initialized, the requestor is removed by executing a delete operation followed by a COMMIT. However, in this scenario, the initialization operation is running within a CMT context and a SQLException was raised indicating that the commit was not allowed. To resolve this, the delete requestor method has been refactored to take into account the CMT context so the commit is not executed if the transaction is managed by the container.

Resolved in Pega Version 8.4.1
A compilation failure on upgraded systems using the JDK 11 compilation of libraries that include Pega 7 functions that have INCLUDE statements that are not supported in JDK 11 was traced to a logic error added when enhancing debug logging. This has been corrected.
