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.

Encoding added for special characters in JFROG filenames
Resolved in Pega Version 8.2.6
A blank screen or the error "Unable to get the file from Repository" appeared when attempting to attach a file from JFROG Repository if the file name contained special characters. This has been resolved by modifying the artificatory URL generation to properly encode special characters during file download.

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.

An error in the logic order of events caused a compilation error for pyClusterAndDBCleaner, leading to old records created by the system/node utilities to not be automatically removed as expected. This has been corrected.

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.
