Restored local blocking queue cache
Resolved in Pega Version 8.6.3
After update, it was not possible to bring up secondary VBD nodes after restarting. Investigation traced this to earlier work done to resolve a memory leak issue, in which stale entries for local blocking queues were removed from cache. This resulted in modifying the queue listener logic to use "cache.getQueueIfPresent(jobId)" instead of "cache.getQueue(jobId)". Because the listener was not creating the cache if it was not present and the cache which held the local blocking queue didn't have the entry for the current remote execution job ID, the caller of the remote execution on Node2 ended up in blocking state forever, waiting on the local blocking queue. To resolve this, the code has been updated to ensure the blocking queue is created and stored in the local queue cache before publishing the remote job message.

TextMask_Encrypted rule added for use with Oracle
Resolved in Pega Version 8.7.2
When a property was being encrypted by propertyEncrypt access control policy and masked by propertyRead access control policy, it showed a "@@getMaskedValueOfText" error. This has been resolved with the addition of a new rule pxTextMask_Encrypted for Oracle product type which will remove extra spaces from the SOURCE string to handle ORACLE specific usecases.

Handling added for external Kafka authorization exception
Resolved in Pega Version 8.7.2
When using external Kafka for stream service, the dataflow was failing with the error 'QueueProcessorDataSubscriberException' when topic create permission was missing. As a workaround, the topics could be pre-created, though a "Topic already exists" warning was generated. To resolve this, the cluster-wide right that a producer needs, IdempotentWrite, has been added. For more information please refer to the link https://docs.confluent.io/platform/current/kafka/authorization.html

Corrected malformed URL
Resolved in Pega Version 8.7.2
The function used in the session timer to log off the user was not working consistently, and attempting to discard a checked-out delegated Rule did discard the rule. Both issues reported the error "HTTP Status 400 - Bad request". This was traced to a badly formed URL, and has been resolved by wrapping the URL with SafeURL_createFromURL.

Addressed intermittent Issues with OAuth2
Resolved in Pega Version 8.7.2
Issues with logging in to a node by way of the access token endpoint were related to the error "JSON web token is rejected during signature verification due to bad signature". This has been resolved by adding clock skew value to the JWT processor bean during validation.

Corrected OAuth jar version for custom Keystore rule
Resolved in Pega Version 8.7.2
Attempting to create a custom JKS and Keystore rule so it could be pointed to the Pega cipher and use the encrypt and decrypt functionalities failed with an error indicating it was not a valid KMS keystore. This was traced to an issue with a jar version mismatch: upon checking the dependencies for the nimbus-oauth-sdk jar, even though version 6.18.1 was specified the system picked the 8.27 version through transitive dependencies, and the 8.27 version doesn't have the needed CommonContentTypes class. This has been resolved by reducing the version to 6.18.1 in conflicting build.gradle.

Check added to ensure Job scheduler executed only once
Resolved in Pega Version 8.7.2
When Node A and Node B woke up at the same time to start executing the job scheduler, both were attempting to update the "now processing" node ID with their ID but only Node A succeeded. This caused Node B to generate a "lock already held" exception, then Node B would try to release the lock and update "now processing" node ID. If Node A released the lock before Node B tried to, then Node B updated the "now processing" nodeID and executed the scheduler, causing it to be run twice. This double-run has been resolved by adding a check for whether the job scheduler has been executed recently before starting it.
