Class Loader cache values wrapped with WeakReference for improved cleanup
Resolved in Pega Version 8.2.7
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.

Resolved Agile Workbench video recording timeout
Resolved in Pega Version 8.2.7
Using the Record Video option thru Agile Workbench to create an Agile Studio item was either taking an excessively long time to finish or was hanging. Research showed that this scenario could arise when the input parameter value crossed more than 50 characters and triggered the interaction threshold for an alert, and has been resolved by updating the system so that query parameters with size more than 50 are not encoded and added to alert logs.

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.

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.

Query added to find time zone for MSSQL database
Resolved in Pega Version 8.7
The exception "com.microsoft.sqlserver.jdbc.SQLServerException: xp_regread() returned error 5, 'Access is denied.'" was generated when the AES agent PushDBSizeInfo was being run. This was traced to the GetDBInfo activity trying to retrieve the time zone of the MSSQL database by executing a query that used a Microsoft SQL routine to read the windows registry to get the current time zone. The error was not due to security within the SQL Server, but instead was caused by Microsoft Windows security related to the permissions on the registry keys for the users under which specific SQL Server processes were running. To resolve this, an update has been made to call a different query which will get the time zone for the SQL Server.

SortPageList method updated for Obj-Sort
Resolved in Pega Version 8.7
Sorting page lists backed by a node level datapage using Obj-Sort was causing a ConcurrentModificationException. This has been resolved by updating the SorterImpl.sortPageList method to use java7CollectionsSort instead of collectionsSortWithInferenceEngineDisabled.

Search behavior change after update corrected
Resolved in Pega Version 8.2.7
After update, changes were seen in the search behavior that included the toggle button at the top left corner of the landing page becoming disabled when re-indexing was in process, the Re-index buttons becoming disabled and a cancel button appearing in place of the re-index button for the specific index category being indexed, indexing done through batch indexers not presenting progress in the document size column every 10 seconds but instead presented the whole row for the index category as blank, and progress being indicated by the changing figures under the Queue Information section on the Search Landing Page. This was due to a conflict in which ruleset was highest after rulesets were imported during update, and has been resolved by updating pzLPSearchManagerReIndexSection to use the correct version of the ruleset.

Data page processing performance improvement
Resolved in Pega Version 8.2.7
After upgrade from Pega 7 to Pega 8, data page processing was noticeably slower. Based on analysis of the issue and results of testing, changes have been made to improve the performance of the query used by the expression parser by using an ClipboardPage API to read values from a Page (ClipboardPageAPI#getString(boolean, String)).

Checks for Apache Tomcat 6 with MSSQL removed
Resolved in Pega Version 8.7
After implementing a specific local Tomcat configuration that removed the Tomcat version number from displaying on Tomcat standard error screens, the error "Tomcat 6 not supported or unable to detect version for custom Tomcat: Apache Tomcat. Contact Pega Customer Support!" appeared and Tomcat failed to start. Because Tomcat 6 was not supported for use with Microsoft SQL Server Systems, Pega used the ServletContext.getServerInfo() method to determine the Tomcat version; if the system used Tomcat 6 or an undetermined version in combination with MSSQL then the system would purposefully not start. As Tomcat 6 is no longer supported in Pega 8.5.2 and above, this check is unnecessary in those versions and the Tomcat version 6 checks in ClassMapImpl have been removed to allow serverAllowsMerge to return as true.
