Resolved exception from expanding deserialized Data Page
Resolved in Pega Version 8.4.5
When using a data page backed by a report definition where the data page data type was Rule- and the virtual page data type was Rule-Obj-Property, serializing and deserializing the data page and then expanding the deserialized data page generated the exception "the reference .pzInsKey is not valid. Reason: .pzInsKey is mapped to class Rule-Obj-Property, which is not the primary class of the list: Rule-; must specify a group name in mapping". The issue occurred only if "Run on Data Page" on the data page was checked and "Report on descendant class instances" on the report definition was unchecked, and has been resolved by updating the runLoadActivity() of DeclarativePageDirectoryImpl to skip setting pyObjClass for the report definition if it already present, i.e. if already set by the loader activity.

Enhancement added for attachment size handling with Kafka
Resolved in Pega Version 8.4.5
Attempting to send an email attachment larger than 2 MB resulted in the error "Caused by: org.apache.kafka.common.errors.RecordTooLargeException: The message is 8101592 bytes when serialized which is larger than the maximum request size you have configured with the max.request.size configuration." This has been resolved by updating the Stream SPI size to 2.0.5-14 to support custom producer configurations. The settings can be passed as environment parameters, for example 'Dstream.producer.max.request.size=500990'.

Email Listener updated to handle double quotes
Resolved in Pega Version 8.4.5
The From field in Requestdata was blank for emails that had a FROM address that contained double quotes, causing them to not be read by the email listener. This has been resolved by modifying the regex pattern to accept double quotes, square brackets, and any ASCII characters between quotes.

IOException logging changed to warn
Resolved in Pega Version 8.4.5
JBoss error messages related to "Exception occurred while closing the Stream" were appearing as a side effect of load on the system or network issues. As this is not a functional concern, the logging for these exceptions has been changed so they will only be shown if warn is enabled.

ExpandStream called before Page-Merge-Into to ensure correct merge
Resolved in Pega Version 8.4.5
The Page-Merge-Into method was not merging the source page into the target page when the use case was run without tracer, but merged properly when run with tracer. This was traced to an intermittent issue with expanding properties, and has been resolved by calling expandStream on the source property if it is unknown prior to checking if the source and target properties are merge compatible.

Archiving updated to include pxobjclass in CTE column list
Resolved in Pega Version 8.4.5
After enabling the case archival feature on a casetype, cases were getting stuck in the Archive-Ready state while being archived, and a 'column not found' error was seen. Investigation showed that the generated SQL statement used to retrieve the resolved case instances used a common table expression (CTE) whose columns were inskey, insclass, and parentinskey, and the query that referenced the CTE was attempting to compare the column pxobjclass when pxobjclass did not exist in the CTE's column list. To resolve this, the CTE column list has been updated to pzinskey, pxobjclass, and parentinskey to prevent the 'column not found error' from occurring, and the query that referenced the CTE was also updated to use the correct column names and aliases.

Methods updated to prevent rounding of JSON response decimals
Resolved in Pega Version 8.4.5
When using a REST connector for an outside service, precision numbers in the JSON response were being rounded or truncated when parsed for the DataSource page. For example, a JSON message with a value like 6045.900000000000000001 became rounded to 6045.9. This happened in both methods used for fast and non-fast processing, and has been resolved by treating the decimal value as a string and then creating a BigDecimal object out of it to avoid truncation in the fast processing scenario, and by adding mapper.enable(DeserializationFeature.USE_BIG_DECIMAL_FOR_FLOATS); for the non-fast processing scenario.

Race condition resolved for input/output pipe streams
Resolved in Pega Version 8.4.5
Writing to S3 using file data set was failing with the error "Exception occurred while uploading file". The system was relying on PipedInputStream for getting the data from the file while uploading, which needs to be connected to PipedOutputStream which holds the data to be uploaded. Investigation showed a race condition was occurring where for some use cases the reading of inputStream was happening before the connection of I/P and O/P streams, resulting in a "Pipe not connected" error. This has been resolved.

Java Bean import updated to handling differences in Java 7 and Java 8
Resolved in Pega Version 8.4.5
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.

GRS support added to Display name and Reply to for SendEmailNotification
Resolved in Pega Version 8.4.5
After upgrade, it was not possible to send email notifications when using a Datapage property in the email account rule. Investigation showed that there was a custom activity being used to call the SendEmailNotification activity and set the pyNotifyAccountName value as email account name by enabling Pass current parameter page, and the custom call was not functioning due to the SendEmailNotification activity being completely refactored in recent versions of the platform where GRS support (which was not a documented feature) was removed. For better backwards compatibility, this issue has been resolved by adding GRS support to Display name (pyFromFullName) and Reply to (pyReplyTo).
