Class Loader cache values wrapped with WeakReference for improved cleanup
Resolved in Pega Version 8.2.8
Out Of Memory exceptions due to Metaspace were observed on Web tier instances running with a max Metaspace size of 2GB. Investigation showed that in PRClassLoaderDB, mLoaderCache values were wrapped with a SoftReference. To resolve this, the Class Loader cache values will be wrapped with a WeakReference, allowing the cache to free memory when it is no longer needed. JVM options has also been added to switch types of References being used if there is a preference.

Check added to minimize Obj-Open-By-Handle error logging
Resolved in Pega Version 8.2.8
When using a Data Type with the "Automatically generate a unique id " option, calling the Save-DataPage method by using the savable data page of the data type finished correctly but showed Obj-Open-By-Handle errors on PegaRules.log. Investigation showed the exception was thrown when running the save plan from DataPageSaverImpl: while attempting to run the save plan, the system does not know whether a parameter (pyGUID in this case) will be required to run the save plan or not, meaning that it can't detect any possible error in DataPageSaverImpl. The implementation instead makes a call to db.open to check if an instance exists and hence logs are thrown. To resolve the error logging, a check has been added: if the save-to class has an autogen key and the savable data page instance doesn't have the autogen key in it, the system will directly call pxCreateRecord. This will avoid a call to db.open to check if instance exists and hence no failed logs will be thrown. This partial change will work only for classes having an autogen key and in cases where the page is trying to create a record by intentionally not passing the key.

Updated handling for validating/saving circumstanced rule on branch
Resolved in Pega Version 8.7
Using 'save as' for an already circumstanced rule with a new property/template caused the Rule-.DictionaryValidation activity to register the error "StandardValidate-CircumPropAlreadyDefined". The same activity Step did not throw an error when saving into Branch. This was traced to the ruleset name not being the same for the branch ruleset due to having _BRANCH_Branch-Name appended to its name, and has been resolved by adding a condition to check for circumstanced rule in a branch.

Updated JSON DT nested page property handling
Resolved in Pega Version 8.6
In a JSON data transform, when using an "Update page" step on a single-page property, as a child step of an "Append and map to" step where a page list property is given, the page list was populated with only one result but the single-page property was treated like a page list and received multiple results. This has been resolved by updating the ClipboardJSONDeserializer implementation and downstream abstractions to support "clipboard only" relations as properties in nested Page Lists.

Process added to clear unneeded requestors from shared pools
Resolved in Pega Version 8.6
Shared service requestor pools were persistently showing a growing count of active requestors when a service was under heavy use, potentially leading to timeouts and exceptions. Investigation showed requestors were moving from active to inactive without updating the pool manager, causing service requestor pools to be held in an inconsistent state with active requestor pools not going down even after completion of service request. To resolve this, a job scheduler process has been added to stabilize the service requestor pools heuristically.

Oracle handling updated for primary key in upgrade DDL
Resolved in Pega Version 8.7
Previously, when a primary key of a table was created Oracle would automatically create a unique index with the same name as the primary key. However, with the introduction of Oracle 19, an optimization was added which will not do that if there is another unique index on the table which contains the column(s) of the primary key. This difference can cause updates to fail with the error "cannot drop index used for enforcement of unique/primary key". This has been resolved by updating the handling for primary key constraint and the corresponding index name.

EnableRedirects property added for REST connections
Resolved in Pega Version 8.6
When implementing a connector with the header “Location” which contains a redirect URI, a 303 response code was expected. Instead, a 400 or 404 error was generated. It was not possible for developers to process the code per their logic in Activity as Connect REST processed 303 responses automatically - i.e. there was no intercept points to implement the suggested approach. To resolve this, the new property "Rule-Connect-REST.pyEnableRedirects" has been added along with a checkbox for the property in "Rule-Connect-REST.pyService" in "Connection" section. Logic has been added in RESTConnector.java to take value of this property and set it on the HTTPClient being used, and a method has been added to HTTPClient interface and ComponentsHTTPClient to use the new value being passed. The default behavior is the same for the REST Connector, but a client can uncheck a checkbox on the REST Connector ruleform to stop the HTTP client from automatically following any compatible 3xx responses.

Mountain time zone format updated
Resolved in Pega Version 8.6
If an operator was created with any calendar instance time zone mapped to "Canada/Mountain" and made unavailable for the current period, routing an assignment to that operator using the standard ToCurrentOperator activity resulted in a null pointer error when the Rule-Utility-Function was executed to find a substitute operator. This was traced to the time zone format Input to DateTimeUtils API (parseDateTimeString) having the wrong time zone, for example, 20200819T080000.000 MDT (CA), and has been resolved by modifying the locale XMLs to remove (CA) from zone code so that MDT (CA) is updated as MDT.
