Configuration added for extending queue processor timeout
Resolved in Pega Version 8.4.5
Alerts for queue processor (QP) items which took more than 15 minutes to run could result in the system marking the node as 'unhealthy'. In environments with Pega Health Check enabled, this would shut down the node gracefully. It was not possible to change this default as it was hardcoded. In order to support systems that may have custom processes that run beyond 15 minutes, a a new setting has been exposed that allows configuration of the interval after which a node with long-running queue processor is marked as unhealthy and is restarted. By default this remains 900000 milliseconds / 900 seconds / 15 minutes, but it may be adjusted up to 24 hours to avoid premature node shutdown. The stale thread detection mechanism will take that setting into account and use the provided value or default to 15 minutes if the value was not provided. In addition, the threshold's units in the UI have been changed from ms to seconds.

InsID will be derived from handle if null for upgrade
Resolved in Pega Version 8.4.5
Upgrade from Pega 7.2.x to Pega 8.4.x failed with a null pointer exception in the “Upgrade Context” target. This was traced to a rule where the pxInsID was null. To resolve this, an update has been made to derive the InsID from handle when needed.

Delayed JS/DF initialization failures will trigger alert
Resolved in Pega Version 8.4.5
In order to ensure better cluster monitoring, a PEGA0102 alert has been added for job registration failure that will be triggered if there are startup issues. The logging will include the JOB_NAME for improved troubleshooting.

Agent restart made more resilient
Resolved in Pega Version 8.4.5
During a timeout outage, agents intermittently encountered a NoClassDefFound error and were disabled. After the database connection was restored, the agents were not automatically restarting. This has been resolved by making the code more resilient to errors; agent will be restarted when a temporary issue is detected, and the restart will be immune to most exceptions.

AES call to mbean disabled
Resolved in Pega Version 8.4.5
Under certain conditions, the AESRemote 'push memory' agent call to the legacy memory management mbean caused unexpected behavior in declarative rules for work running in data flows and queue processors. This has been resolved at this time by overriding the push memory usage agent activity to skip mbean and connect REST.

Corrected race condition that caused JobScheduler error
Resolved in Pega Version 8.4.5
A race condition between the pzInitializeQueueProcessors and pyPersistNodeState job schedulers that both run at platform's start was causing a null pointer exception with the error "com.pega.platform.executor.jobscheduler.scheduler.JobExecutionException: Activity execution failed with [PRRuntimeException]". This has been resolved by moving the QueueProcessor initialization process from JobScheduler to StartupTask.

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.
