Timezone.getDefault function replaced for performance improvement
Resolved in Pega Version 8.6
Blocking threads were seen around the GregorianCalendarFactory.clearObject(Object) function, leading to an adverse impact on the performance.TimeZone.getDefault() is a synchronized method call, and under high load this method caused contention when more date-related APIs were invoked. To resolve this, Timezone.getDefault() has been removed and the function has been assigned to a static variable used in the clearObject() API.

Java Bean import updated to handling differences in Java 7 and Java 8
Resolved in Pega Version 8.7
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.

Export to Excel cell style control added
Resolved in Pega Version 8.5
If a column was formatted with an auto generated numeric control, a new cell style was generated for every row during the export to Excel process. Since there is a limit on the amount of cell styles, once the number of rows in the file was greater than 64000 an error was generated. To resolve this, the system will disable the creation of a new cell style for every instance when an auto-generated numeric control is used.

New Rule-Utility-Function added to allow customizing filename formatting in repository
Resolved in Pega Version 8.6
When using S3 as file storage, uploading a file with a name such as "sample.tar.gz" resulted in the file name in the repository being formatted as "sample.tar_.gz" instead of the expected "sample_.tar.gz". This was caused by the handling in pzSaveToRepository, which was meant to include the CaseID for the customer use case of same-name attachments on every instance of a case. In order to handle attachments with multiple file extensions such as "<FILE_NAME>.tar.gz", the logic for the fileName formatting has been moved from pzSaveToRepository to the new Rule-Utility-Function pyFormatAttachmentName so that is is possible to override and customize the behavior.

ClipboardToJSON Serializer enhanced
Resolved in Pega Version 8.5
After creating a JSON data transform with the top level structure set to Object and a step that mapped a Pagelist in clipboard to an Array of Objects in JSON, calling the data transform in Serialize mode resulted in a JSON mapping exception. This was a missed usecase for using the JSON serializer with nested pagelists in page, and has been resolved by adding pagegroup support for data transform serialization and skipping pagegroup serialization when automapped.

Obj-Browse will retrieve more than 50 records
Resolved in Pega Version 8.5
After performing multiple skims, a newly added property was not retrieved when an Obj-Browse was performed. In Obj-Browse action, when a class is mapped to an external table and does not contain BLOB column pzpvstream, in a specific case where pxObjClass value is a reference to a parameter, a list of properties mapped to the class explicitly by querying pr4_rule_property table using NativeSQL is fetched. This call by default returns only 50 records: in cases where there are more than 50 properties for an external class, some of the properties from the obj-browse response mapping are therefore missed. To resolve this, the limit of 50 records has been removed from this NativeSQL call.

Class Loader cache values wrapped with WeakReference for improved cleanup
Resolved in Pega Version 8.5
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.

Support added for tracing PageList during automations
Resolved in Pega Version 8.5
When using the out-of-the-box email reply on an email triage case, an exception was observed in the tracer stating "com.pega.pegarules.pub.clipboard.WrongModeException: The property To.pxResults was of mode Page List while com.pega.pegarules.data.internal.clipboard.ClipboardPropertyImpl.getObjectValue() was expecting Java Object mode." This has been resolved by adding support for tracing PageList during automations.
