Null check added for missing compiler path
Resolved in Pega Version 8.7
After upgrading from Pega 7.3 to Pega 8.6, libraries were not loading correctly and a java error was seen. This was traced to the compiler default path values not getting picked from DSS / settings->compiler->Default paths, which was caused by a null value for the DASS setting in the systemSettings map. To resolve this, a null check has been added and an update has been made to use getEngineDynamic to ensure this setting is picked on node startup.

Handling updated for validating properties with a FieldValue
Resolved in Pega Version 8.7
Running a report which included a property calculated by a Declare Expression generated an excessive number of log messages indicating "Error occurred while executing forward chaining on page 'pyReportContentPage.pxResults". Degraded system performance, stack overflow, and other similar issues were seen. This was traced to an infinite loop that resulted from a missed use case for a Report Definition with a Target property of a Declare Expression with FieldValue, and has been resolved by disabling autochain while validating properties with a FieldValue.

Enhanced handling for URLs with multiple Connect-REST parameters
Resolved in Pega Version 7.1.9
When there were two parameters present in a URL, the Connect-REST parsing was incorrect because only the outer braces were removed (the first brace from the first parameter and the second brace from the second parameter). To handle this correctly, the URL logic has been broken out into a separate activity. In addition, new information such as body and content type has been added to the results.

ServicePackage threads properly released
Resolved in Pega Version 8.7
After completing a system stress test, the requestor pool threads for the ServicePackage were not released. Investigation showed that the threads were waiting for Data Pages to be loaded in the background even though there was no background job corresponding to those data pages in the Async Services pool. This has been resolved by making an update to avoid removing the object handlers when the load-datapage finds that an entry exists with a NOT_STARTED state.

Handling added to StreamChangeTracker for non-String mode
Resolved in Pega Version 8.7
Incorrect StreamChangeTracker mode properties were being tracked for value changes. Investigation showed this was due to the StreamChangeTracker.trackValueChanges API tracking value changes on properties of mode page and page list, which resulted in logging a WrongModeException in the logs. This has been resolved by updating the behavior of the StreamChangeTracker.trackValueChanges API to return false when value change tracking is invoked for a property other than mode String.

Added special character decoding for outgoing email attachments
Resolved in Pega Version 7.1.9
Previously, code was added to the system to fix the cross-OS issue of special characters in file attachment names like [,],(,),{,},\,. As part of the fix, the file names are encoded before being saved to the database. However, when those attachment are retrieved and sent out again as email attachments, the encoded characters were visible instead of the decoded values. To complete the decoding process, the file name will be handled with StringUtils.decodeCrossOSString(strfilename).

Added escaping for JSON special characters in REST
Resolved in Pega Version 7.1.9
When a REST Service was called and returned a property value which contained a character having special meaning for JSON (like ", \, /, backspace, formfeed, newline, carriage return, horizontal tab, or hexadecimal digits), the JSON string could not be parsed. In order to resolve this, escaping has been added to the outbound JSON text to arrive at a valid JSON. Since this adds to performance overhead as each and every character must be checked, a DSS has been added to escape the JSON conditionally.

Corrected REST logic for missing/blank query parameters
Resolved in Pega Version 7.1.9
When running a REST connector with a resource path that contained multiple parameterized areas of the query string where the value of the first and/or last query string parameters were blank or missing, the request URL was missing the query string parts that have an equals sign delimiter but a blank/empty value. This was unexpected behavior traced to a change in the generation logic, and the system has been modified to produce the expected behavior of query parameters with blank values appearing as "val1=" instead of not appearing or missing the equals sign.

Links to specifications persist appropriately
Resolved in Pega Version 8.7
When linking Rules to Specifications, check-ins of some unrelated rules deleted the link. Investigation showed the deletion happened in the pzHandleLinksPostCheckIn activity, and was caused by an empty parameter page name that caused pcInsKey to not have a value, so all links returned by "Obj-Browse" were later deleted. To resolve this, an update has been made to insure the "Pass current parameter page" option in step 2 of the Connect REST PostCheckIn activity is enabled so that the downstream activity pzHandleLinksPostCheckIn behaves as expected.
