Clipboard page fixed for evaluating Rule-Access-When condition
Resolved in Pega Version 7.4
After logging into the application and accessing the work objects from the worklist, a sporadic error would appear when evaluating Rule-Access-When conditions even though the required page being evaluated against has the data populated. Evaluation showed the execution of the Rule-Access-When condition was failing because the incoming primary page was null, and this was traced to an incorrect clipboard page name in AccessEvaluatior.java. This has been fixed.

cluster rule watch lock expires on crash
Resolved in Pega Version 7.4
If the cluster rule watch was in progress and the browser / system crashed, the rule watch became locked until the system (cluster) was restarted. In this case, the disconnect command from Req1 has an encrypted requestor ID because it is an unauthenticated requestor, leading to all String-matches failing. A hook to delete all entries in the distributed rule watch map for a given requestor during its clean up has now been added to resolve this.

JSON key sort performance improvements
Resolved in Pega Version 7.4
Sorting the keys in the JSON output was causing a synchronization bottleneck. The acquisition of the Collator object was synchronized in JDK code when it did not need to be, and the call to Collator.getInstance() has now been replaced with a call to Collator.getInstance(Locale.getDefault()) in order to improve performance.

Autopopulate disabled for clearPageMessages API
Resolved in Pega Version 7.4
A concurrent modification issue was seen in the logs while adding Location, and was traced to an exception in the clearPageMessages API caused by autopopulation. In order to ensure consistent behavior throughout the system, a decision was made to disable Autopopulate in all of the messages-related parent APIs that are NOT expected to change the data on the object.

IOException communication improvements for BIX extractions
Resolved in Pega Version 7.4
An enhancement has been added to improve communications regarding IOExceptions for ExtractImpl. When the exception occurs while trying to close the file, the previous INFO message in the PegaRULES log file has been modified to be a warning message that will include the actual IOEX.getMessage(). This will also be in the PegaBIX log.

Set urandom for Unix/Linux to resolve connection reset
Resolved in Pega Version 7.4
On a Unix system where securerandom.source is not set to /dev/random, running an installation on Oracle using a new version of the JDBC driver caused connection reset. To fix this, Djava.security.egd=file:///dev/urandom has been added to prpcUtils.xml and migrateSystem.xml for use when the database is Oracle and environment is Linux/Unix.

Rollback information collection optimization
Resolved in Pega Version 7.4
During rollback information collection, a rule inventory is regenerated. This checking can include searching for instances that no longer exist in the database, potentially causing performance issues. In order to optimize the function and reduce unneeded logging, the rollback information collection process has been updated to reuse the rule inventory.
