SR-D37421 · Issue 514593

Cross-site scripting security added to Marketing Offers

Resolved in Pega Version 8.1.8

Cross-site scripting protections have been added to Marketing Offers, which had a potential vulnerability when using Firefox.

SR-D45608 · Issue 519902

Correct service instance name passed for data flow in DSMStatus

Resolved in Pega Version 8.1.8

When using the Connect-HTTP service "DSMStatus" to provide the node and status information as seen on the various tabs of the Designer Studio > Decisioning > Infrastructure > Services landing page, using DataFlow as the service parameter for the HTTP service method resulted in an empty response when the expectation was to get the information regarding the cluster details of Dataflow node type. This was traced to the service instance name not being parsed correctly when used for Data Flow services, and has been resolved by ensuring the correct service instance name is passed for this use.

SR-D47618 · Issue 516300

Statistic rounding error in ADMSnapshot Agent with Oracle corrected

Resolved in Pega Version 8.1.8

While running the ADMSnapshot Agent, the exception "internal.mgmt.Executable) ERROR com.pega.decision.adm.client.ADMException: Failed to complete ADM Data Mart snapshot" was seen. This was traced to an issue with the rounding of performance statistics when using Oracle, and has been resolved.

SR-D54218 · Issue 518599

Deadlock in static Initialization of IntList resolved

Resolved in Pega Version 8.1.8

JVM Deadlock was seen related to the static Initialization of a subclass field in class com.pega.decision.strategy.ssa.runtime.collections.api.IntList . Thread dumps showed threads in RUNNABLE State that were parked to wait for class initialization, and this was traced to a missed sonar alert which failed in multi-threading. To resolve this, the system handling has been updated to prevent potential deadlock.

SR-D60268 · Issue 521460

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.

SR-D68558 · Issue 536676

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.

SR-D85095 · Issue 546340

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.

SR-116508 · Issue 170253

Large flow handling improved for IE8

Resolved in Pega Version 7.1.7

When opening a large flow in IE8 which includes multiple sub flows, a long-running script warning is displayed. This is caused by too many calls being executed at once on IE8, and has been remedied by turning on the asyncProcessing parameter for IE8.

SR-116818 · Issue 167121

Corrected swim lane routing with shapes

Resolved in Pega Version 7.1.7

While using swim lanes, adding shapes into the flow caused unexpected and random behavior of the process modeler including failure to return control to the user after saving. This error was related to routing handling when swim lanes are present, and has been corrected.

SR-117228 · Issue 168249

Resolved issues with Flow shapes distributed across Swim Lanes

Resolved in Pega Version 7.1.7

Pool size is maintained as both pixels and inches, but auto conversion was failing if the pool dimension was very large. This created an error where saving a flow rule could cause the pool to drastically shrink (for example, 20 inches becoming 20 pixels). In order to maintain the proper dimensions, a check has been added for pool and swimlane to ensure the proper inch/pixel conversions.
