Locking and classmap improvements
Resolved in Pega Version 8.4.4
Threads were getting stuck inside classMap and tableInformationMap, causing nodes to go down. This was traced to issues with classmap performance and locking, and has been resolved by replacing the lock library with a newer version and refactoring the tableInformationMapImpl class to use a concurrent hashmap instead.

Resolved parent lock sending child item to broken queue
Resolved in Pega Version 8.4.4
If the ServiceLevelEvents agent tried to process the queue item for a child case but encountered a lock error because the parent case was locked, the queue item was immediately going to the Broken-Process status instead of re-queueing the item to try again in 15 minutes. If the property was set to 'Copy data from a data page', the item was re-queued. To resolve this, the unwind and forward chain calls have been reversed. A dynamic system setting is available to reset the change.

Adding handling for property without parent page
Resolved in Pega Version 8.4.4
Filtering was not working for a DateTime control in an optimized grid with embedded property which was a function alias defined in a report definition referenced by a Data Page. This was traced to the system assuming that every property has a parent page, which this use case did not. To resolve this, an update has been made that will return null for the parentGroupOrListProp if one does not exist.

Updated JSON DT nested page property handling
Resolved in Pega Version 8.4.4
In a JSON data transform, when using an "Update page" step on a single-page property, as a child step of an "Append and map to" step where a pagelist property is given, the pagelist was populated with only one result but the single-page property was treated like a pagelist and received multiple results. This has been resolved by updating the ClipboardJSONDeserializer implementation and downstream abstractions to support "clipboard only" relations as properties in nested PageLists.

Handling added for empty back link in BLOB
Resolved in Pega Version 8.4.4
A DirectStreamContainerV7 Exception (BLOB Corruption) was seen when opening a work object that expanded a certain property. This was traced to an empty back link present in the BLOB: during deserialization, the exception was thrown while trying to parse that empty back link. To resolved this, an update has been made which will parse the empty back link information properly.

Data Page Save correct in batch mode
Resolved in Pega Version 8.4.4
After configuring a List type savable Data Page with save activity in Code-Pega-List, the save data page was triggered from utility of flow from the queue processor to handle queueing 10k data items and creating 10k work objects. When this was run, a field dpClassName was being changed by different threads in DataPageSaverImpl.java. This has been resolved by making the class DataPageSaverImpl.java stateless to ensure thread safety.

Added handling to avoid class cast exception
Resolved in Pega Version 8.4.4
The error "doMaintain errorjava.lang.ClassCastException: java.util.HashMap cannot be cast to com.pega.pegarules.priv.factory.SequencedEntry" appeared in production numerous times per day, leading to exceptions. Investigation showed this was being triggered from the activity Show-harness, and was traced to the ConcurrentMostRecentlyUsedMap eviction method casting entries to Sequenced entries. There is no such check while putting entries. To resolve this, a wrapper has been added over the ConcurrentMostRecentlyUsedMap object to avoid a class cast exception.
