Performance and thread-handling improvements for SSA
Resolved in Pega Version 8.1.8
The SecureRandom class was used internally by SSAExecutionContext indirectly via UUID generation. Because this exhibited performance issues on some Linux environments, UUID has been replaced with static AtomicLong. In addition, a memory leak was observed when the strategy (SSA) execution resulted in an exception, and the strategy template has been modified to gracefully shutdown the VM under all circumstances. Thread-safety measures have also been tuned to be more fine-grained to reduce the potential thread contention that was seen while borrowing the SSAInterpreter object from SSAInterpreterPool.

Timing updated for Cassandra session change thread lock
Resolved in Pega Version 8.1.8
An issue with unresponsive nodes was traced to the method used for notifications about Cassandra session changes. A thread trying to obtain a Cassandra session acquired a read lock, then if it then determined that a new session had to be created it would also acquire a write lock, preventing other nodes from trying to acquire the session. After creating a session, the thread notified all session change listeners while holding the write lock, causing deadlock with dependent services. To resolve this, the timing has been updated by moving the session change notification to the listeners outside of the section guarded by the lock.

Updated COUNT logic for strategies with ssavm set to true
Resolved in Pega Version 8.1.8
An error was seen when attempting to save a strategy after setting ssavm to true, indicating an issue in the “COUNT” method in Group By shape. Since the source field is not used and does not need to be evaluated here, the system has been updated to ignore the source field if the operation is COUNT.

Guided tour popups handling added for right-to-left language locales
Resolved in Pega Version 8.1.8
Guided Tour Popups were still appearing in the default EN location after switching to the ar_AR locale. This was traced to a missed use case for locales using a right-to-left mode such as Arabic or Hebrew, and has been resolved by updating the guided tour engine openPopOver function to account for the HTML tag dir attribute for value of "rtl". This will anchor the pop over to rightBottom / and display the arrow on the rightTop instead of leftBottom / leftTop.

pyStatusWork for parent case correctly resolved
Resolved in Pega Version 8.1.8
pyStatusWork was not getting updated for the parent case even though the case passed through the resolution stage. This was an unintended side effect of work done regarding resolving a subcase if it was opened from the review harness, and has been resolved by updating the findPageByHandle activity to return the correct page when there are multiple pages with the same key.

Updated Decision Table validation for multiple OR conditions
Resolved in Pega Version 8.1.8
When the Decision Table had multiple OR conditions, the table was verified as consistent even when two rows had the same value. Analysis showed that when Show Conflicts encountered multiple 'or' conditions in a row that matched the same conditions in other rows, it considered them to be different rows. This has been corrected.

Resolved ruleset save issue for Google Chrome/IE
Resolved in Pega Version 8.1.8
When using particular versions of Google Chrome or IE, the intermittent error "pyComponentInterfaceClass: <user> does not exist or is not a valid entry for this ruleset and its prerequisites" appeared when attempting to validate an application, and the ruleset could not be saved. This was traced to changes made in the browser around password handling, and has been resolved by explicitly clearing out the pyComponentInterfaceClass if that value is not in use.

Resolved null-pointer exception in Expression Builder launch from activity rule
Resolved in Pega Version 8.1.8
A NullPointerException occurred in SafeURL when trying to launch the Expression Builder from an activity rule. This was trasced to a failure to get a value property in a target field due to the target element and its parent element containing the same value for name attribute. This caused the parent element to be considered instead of the target element. To resolve this, the search for the target element in parent tag will use '$p' along with 'target element name' in query selector.
