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.

Empty hidden elements stripped when AAR proxy in use
Resolved in Pega Version 7.4
When using IIS WebServer and AAR proxy configuration with high security settings, submitting a form through Microsoft Internet Explorer with hidden input fields that did not have a name attribute resulted in a blank parameter name and value being added. This formed an invalid request that returned a HTTP 200 with no error message. Because Microsoft Internet Explorer does not ignore elements which have empty names, the code has been updated to remove name attributes on pycustomerrorsection hidden elements.

Corrected Boolean option documentation for BIX
Resolved in Pega Version 7.4
In the user Guide for BIX, the "Optional command-line BIX parameters" section states the -B option affects how Boolean values are published, giving '01' as a valid option. However, attempting to use it generated a runtime exception stating that it was an unsupported value. This issue was caused a documentation error, and the files have now been updated to correctly indicate the option is "10".

ABAC exception handling added
Resolved in Pega Version 7.4
After creating an access control policy and access control policy condition on a data class that shows in the Data Explorer, defining the condition such that it was always false and then clicking on the class on which the policy was just defined generated an error. If the policy was withdrawn and then clicked on again, it appeared as expected. This was reproducible only when ABAC was enabled, and handling for an exception generated in this scenario has been added.

Object contention resolved to improve getPOJO performance
Resolved in Pega Version 7.4
Object pool contention issues were seen related to getPOJO and getDelegate. This was traced to the legacy class GenericObjectFactoryPool, where a hashmap was being guarded with a synchronized block for multi-thread access. This process has now been replaced with a concurrenthashmap to do the same but with thread contention.
